Pesticide Intermediates

It can be used as raw materials for synthetic medicine, dyes and resins, and can be used to prepare fertilizer synergists, herbicides, livestock insect repellents, rubber accelerators, dye intermediates, etc.

Chemical analysis reagent, used as gas chromatography stationary solution. It is used as solvent, non-toxic antifreeze, food emulsifier, hygroscopic agent, and used in organic synthesis. Pharmaceutical, food industry.

It is a new type of highly efficient catalyst widely used in chemical synthesis. It has high catalytic ability in acylation, alkylation, etherification and other types of reactions in organic synthesis, drug synthesis, pesticide, dye, perfume synthesis, and has extremely obvious effect on improving the yield.

Pentaerythritol, as a quaternary alcohol, is easy to be esterified to form acids and esters, so it is mostly used as raw material of alkyd resin coatings, mainly used as building coatings and automotive primer. Pentaerythritol tetranitrate can be obtained by esterification of pentaerythritol and concentrated nitric acid at 5 ~ 15 ℃ in industry. It is a kind of high-performance and strong explosive with higher explosive power than TNT. It is often used as booster or mixed with TNT. It was used extensively in the Second World War. It is a long-acting vasodilator and can treat angina pectoris. Pentaerythritol rosin ester can be prepared by the reaction of pentaerythritol and rosin acid. It can be mixed with dry oil to obtain a coating with good hardness, water resistance and weather resistance. It can be used for varnishes, floor inks, etc. An alkyd resin coating can be prepared by esterification polycondensation of pentaerythritol or glycerin with phthalic anhydride and fatty acid. The properties of alkyd resin can be improved by using different kinds and different amounts of fatty acids, making it suitable for various needs of coatings. It is widely used as metal, wood surface coating, for bridges, railways, derricks, housing construction and other commonly used industrial paint and architectural paint. Alkyd resin has developed rapidly since it entered industrial production in 1927 due to its low price, easy availability of raw materials, easy modification, strong adaptability and good comprehensiveness.

It can be used in organic synthesis intermediate, pesticide industry to produce fungicide phosphoramide, perfume and film.
