Solvent

Dimethylformamide is a good organic solvent and widely used. In petrochemical industry, dimethylformamide can be used as gas absorbent to separate and refine gas. As a washing and curing agent in polyurethane industry, it is mainly used in wet synthetic leather production; As a solvent in acrylic fiber industry, it is mainly used in dry spinning production of acrylic fiber; In the electronic industry as tinning parts of quenching and circuit board cleaning, etc; Other industries include carriers of dangerous gases, solvents for drug crystallization, adhesives, etc. In organic reactions, dimethylformamide is not only widely used as a solvent, but also an important intermediate in organic synthesis. It can be used to produce Chlordimeform in pesticide industry; In the pharmaceutical industry, it can be used for the synthesis of iodamine pyrimidine, doxycycline, cortisone, vitamin B6, iodoside, qupinjing, thiadiazine, n-formylsarcoma lysin, antineoplastic acid, methoxyaryl mustard, benazepril, cyclohexylnitrosourea, furafluorouracil, hemostatic acid, betamethasone, megestrol, danvita, chlorphenamine and sulfonamides. Dimethylformamide plays a catalytic role in hydrogenation, dehydrogenation, dehydration and dehydrohalogenation, which reduces the reaction temperature and improves the purity of the product.

N-propanol is directly used as solvent or synthesis of propyl acetate. In many cases, it can replace ethanol with low boiling point for coating solvent, printing ink, cosmetics, etc. It is used to produce n-propylamine, an intermediate of medicine and pesticide, feed additives, synthetic spices, etc. N-propanol is used in the pharmaceutical industry to produce probenecid, sodium valproate, erythromycin, dianjian'an, adhesive hemostatic agent BCA, propyl thiamine, dipropyl 2,5-pyridine dicarboxylic acid, etc; Various esters synthesized from n-propanol are used in food additives, plasticizers, spices and many other aspects. The derivatives of n-propanol, especially di-n-propylamine, are widely used in medicine and pesticide production. They are used to produce pesticides such as amisulfuron, bactericide, isoprotolin, metoclopramide, sulfrotolin, florol, etc.

Triethyl phosphate is widely used in textile and paper products, as plasticizer, non reactive flame retardant, hardener and accelerator, lubricant, flotation agent, defoamer, emulsifier, stabilizer or extractant in plastics and coatings.

1,2-dichloropropane is mainly used in paints and inks. It is used to prepare paints, inks, diluents and PVC adhesives. It is an excellent organic solvent, which can replace the relevant uses of benzene such as xylene. It is used to make benzene free banana water and polyurethane diluents, which are soluble with organic solvents such as benzene, ketone and ester. As a by-product of Po produced by chlorohydrin method, it is the main raw material for thinner production and used as paint thinner. Low toxicity and environmental protection, instead of toluene and xylene, it is widely used in benzene free Tianna water.

DiBP is one of the main plasticizers commonly used. It can be used as plasticizer for cellulose resin, vinyl resin, nitrile rubber and chlorinated rubber. The plasticizing efficiency is similar to that of DBP, with excellent solubility, dispersion and adhesion. This product has good compatibility with pigments. It can be used for coloring films, artificial leather and plastic products. It can also be used as a softener of natural rubber and synthetic rubber to improve the resilience of products. It can be used as a substitute for DBP.
