China1,4-Butanediol is an important organic and fine chemical raw material used in the production of tetrahydrofuran, Y-butanone, and polyethylene terephthalate. It can also be used to prepare N-methylpyrrolidone, N-vinylpyrrolidone and other pyrrolidone derivatives, as well as vitamin B6 and pesticides. 1,4-Butanediol has good hygroscopicity and flexibility, and can be used as a gelatin softening agent and water-absorbing agent, as well as a treatment agent for glass paper and other unused papers. It is widely used as a solvent, plasticizer, lubricant, humidifying agent, softening agent, adhesive, and brightener in electroplating industries.

Chemical properties This product is a transparent liquid with a chromaticity below 30. Relative density 1.0536, boiling point 77 ℃ (666.61Pa), refractive index 1.4443, flash point (open cup) 100 ℃, freezing point below -60 ℃. The glass transition temperature of the polymer is -70 ℃. Dissolve in water and general organic solvents. It can be mixed with water in any proportion. Purpose It can be used as a modifier in the production of thermosetting coatings, adhesives, fiber treatment agents, and synthetic resin copolymers. It can also be used as one of the main cross-linking functional group monomers for acrylic resins. Production method Acrylic acid and epoxy propane undergo an addition reaction in the presence of a catalyst and polymerization inhibitor to produce a crude product of 2-hydroxypropyl acrylate, which is then degassed and distilled to obtain the final product. Acrylic acid is obtained by oxidation of propylene or hydrolysis of acrylonitrile.

Gralic oil Allicin35%~55% CAS NO.8008-99-9 A volatile liquid ranging from pale yellow to reddish-brown, with a strong garlic odor. It is insoluble in water, glycerin, and propylene glycol, with a relative density of 1.050-1.059 and a refractive index of 1.550-1.580. Its chemical properties are relatively stable, but it easily decomposes when exposed to alkali.
Abamectin is a mixture of avermectins which are derived from the soil bacterium Streptomyces avermitilis. It contains > 80% avermectin B1a and < 20% avermectin B1b. These two components, B1a and B1b have very similar biological and toxicological properties. It’s an effective insecticide and acaricide used to control a wide range insect and mite pests in agronomic, fruit, vegetable and ornamental crops, and it is used by homeowners for control of fire ants. Doses of 50 to 200 ug/kg of ivermectin, is widely used to treat humans in the WHO onchocerciasis (river blindness) program.
