Applications of Trimethylolpropane/TMP(CAS 77-99-6)

1. Synthesis of alkoxide resins

Since the trimethylolpropane molecule contains a special molecular structure with three primary hydroxyl groups, it can either replace glycerol in the synthesis of alkoxide resin, or replace or share with polyols such as pivaloyl glycol and pentaerythritol in the production of alkoxide resin, its properties are better compared with those of alkoxide resin prepared with various polyols such as glycerol, pivaloyl glycol, and pentaerythritol, which have better resistance to hydrolysis, soothing reaction stability, alkali resistance, and thermal stability, In addition, it has the advantages of bright color, high color retention, and resistance to temperature and rapid drying, and is particularly useful for producing road sign paint, light cover paint, and is also used as a topcoat for cars, electric freezers, washing machines, bicycles, aviation, as well as navigation. Alkoxylic acid resins synthesized from trimethylolpropane have good phase solubility with amino resins and can be used as raw materials for polyurethane coatings, as well as for higher coatings such as carbamate based self-drying lacquers and drying lacquers.

2. Synthesis of higher lubricants

Esters of trimethylolpropane can be used for the synthesis of higher lubricants. Lubricants synthesized from trimethylolpropane as raw material have many advantages such as low melting point, high viscosity, high burn point, and soothing reaction performance, and are widely used for lubrication of aircraft engines, which can reach above 200 ° C using temperature, but also for lubrication of automotive engines, air compressors, as well as electric freezers, which are superior to those synthesized from pivaloyl glycol and other raw materials. In addition, synthetic oils made with main trimethylolpropane can also be used in the processing of bearing steels.

3. Production of polyester and polyurethane foams

Trimethylolpropane is widely used in the production of polyurethane elastomers and polyurethane foam. Carbamates, produced from trimethylolpropane and toluene diisocyanate (TDI), 1,3 - butanediol, exhibit high hardness, elasticity, wear resistance and soothing aging, and are widely used in the manufacturing of solid core tire, transport belt, sponges as well as in thermal processing and aerospace industries; Polyether polyols with free hydroxyl groups, produced by the reaction of trimethylolpropane with ethylene oxide or propylene oxide, are the main raw materials for the production of soft polyurethane foam plastics, and the synthesized polyurethanes, which have both rubber and plastic double properties, are highly elastic, wear and tear resistant, rinse resistant, and long-time as well as fluorescence and vivid colors, and are particularly useful for the production of road sign lacquers, hood light lacquers, electrophoretic lacquers, etc., but also for the manufacture of aircraft, cars, trains The pads, backs, steering discs, instruments, armrests, insurance bars of tire for soles, solid core tire, transfer belts, sponges, spaceflight, thermal processing, as well as materials, etc; Polyesters synthesized from trimethylolpropane and glyceromaleic acid, which exhibit climatic resistance, radiation resistance, softness as well as reduced polyester self stainability, are widely used as building materials as well as substitutes in the leather industry. In terms of foam production, trihydroxymethylpropylane also substitutes partially or totally for 1,4-butanediol.

4. Preparation of plasticizers

The complex ester produced by the reaction of trimethylolpropane with a monobasic aromatic acid, C5-C9 fatty acid, in the presence of a nonacid catalyst is a well-established plasticizer, and the polymer incorporating this ester exhibits excellent high temperature and hydrolysis resistance as well as acid-base properties, and it has a good affinity with polyvinyl chloride (PVC), and PVC plastics containing this plasticizer can still maintain good electrical insulation in aqueous environments. In addition, trimethylolpropane can also replace isodecyl alcohol for the production of diisodecyl phthalate, an important higher plasticizer, in the production of special coatings such as electrical wiring.

5. Preparation of emulsifiers

Semisolid compounds produced by partial esterification of trimethylolpropane with monobasic fatty acids followed by reaction with ethylene oxide show good emulsification of oil/water emulsion and can be used as emulsifiers in medicine and cosmetics. Nonionic surfactants produced by the addition of trimethylolpropane and propylene oxide have excellent emulsification and wettability properties. Alkoxylic acid resins made of trimethylolpropane and high molecular weight binary fatty acids containing two double bonds are water/oil type emulsifiers and have a wide range of applications in textile and dyeing industries.

6. Preparation of liquid fuel additives

The liquid fuel additive was prepared by esterification of trimethylolpropane with oleic acid followed bya reaction with paraformaldehyde. Add 0 The liquid fuel after 5 to 1% of this substance is purified to exhaust gas without a vaporization unit.

7. Production of trimethylolpropane triacrylate (TMPTA)

Trihydroxymethyl propane triacrylate (TMPTA), obtained from the reaction between trihydroxymethyl propane and acrylic acid esterification, is a widely used multifunctional enoate active diluent in the field of radiation curing, which has high content of double bonds, rapid curing, wear and solvent resistance, and is mainly used as a reactive diluent for ultraviolet curing coatings and inks. Acts as a dilution before UV irradiation, while after irradiation, it itself also reacts, thus forming part of the cured membrane. TMPTA can also be used to produce unsaturated polyester glass steel, reinforced plastics, special glycolic acid resins, adhesives, synthetic oils, rosin esters, synthetic fiber AIDS, and for the processing of chemical membrane sheets.

8. Production of trimethylolpropane trimethacrylate (TMPTM)

Trimethylolpropane trimethacrylate (TMPTM) obtained by esterification of trimethylolpropane with methacrylic acid is a multi-functional energy group monomers, which can be used for the sizing of PVC latex (antiseptic shoes, etc.) and for cross-linking PVC coated threads, can also be used as curing agents for anaerobic binders, rubber (propylene glycol) cross linkers and inks, and can also be used for the modification of coatings and resins.

9. Production of trimethylolpropane triglycidyl ester (TMPTE)

Trimethylolpropane triglycidyl ester (TMPTE), produced by the reaction of trimethylolpropane and epichlorohydrin, can be used as a reactive diluent for epoxy resins (epoxy coatings), a modifier of resins for polyesters and material materials, a fiber processer (antifouling treatment), and a modifier of bonding, among others.

10. Other aspects

43 fire-resistant polyethers, prepared by heating reaction of trihydroxymethyl propane with phosphoric acid, dehydration in a vacuum, and polycondensation with excess epichlorohydrin, have good flame retardant properties and can react with isocyanates to produce flame-retardant polyurethane resins; In addition, trimethylolpropane has been used in the synthesis of chain extenders, textile AIDS, curing agents, release agents, catalysts, heat stabilizers of polyvinyl chloride (PVC) resins, and a variety of fine chemicals for the manufacture of liquid patch electrodes with strong selectivity for sodium ions, among others.

The by-product polyester polyol obtained in the production process of TMP can be used as the production raw material of aromatic polyester polyol.

The Difference Between Trimethylolpropane and Trimethylolethane Performance

Both trimethylolpropane (TMP) and trimethylolethane (TME) belong to the polyol family, and although they are structurally similar, they have many markedly different properties. For example, TME is harder and has better temperature resistance. The neopentyl structure of TME endows it with good application properties. TME esters have better thermal stability, strong heat resistance, light resistance, and hydrolysis resistance. The hydrolysis index is related to corrosion resistance and stability. Therefore, TME is the binder of choice for high-performance coatings, especially in waterborne alkyd and polyester varnishes. TMP is mainly used as a chain extender for polyurethane, PVC polymerization, HIPS and other chain extenders, light (heat) curing agent, etc. The application fields can complement each other and are irreplaceable different polyol products.
