Trihydroxymethyl Propane Palm Kernel Ester is light yellow oil liquid with the acid value 2mgKOH/g and the saponification value 218-238mgKOH/g. Soluble in water, alcohols, glycerol, N, N-dimethylformamide, partly soluble in acetone, ethyl acetate, micro-soluble carbon tetrachloride, chloroform and ether, insoluble aliphatic hydrocarbons, aromatic hydrocarbons and chlorinated hydrocarbons. Their hygroscopicity about 50% glycerol. It is used in daily chemical raw materials, fiber lubricant and oil additives.
Trihydroxymethyl Propane Palm Kernel Ester appears as a white lamellae. 58.8 ° C melting point, boiling point of 295 ° C and 160 ° C (0.67kPa). Butyraldehyde and formaldehyde in alkaline conditions under Aldol reaction fluid concentration desalination, reuse ion exchange resin bleaching, purification, with the final film evaporator evaporation, cooling, rolling film, in refined. The relative density (20 / 4 ° C) 1.0889, flash point (open cup) 180 ° C and 193 ° C to ignite, melting 183.4kJ/mol hot, burning hot 3615kJ/mol. It is also widely used in polyester and polyurethane foam production, but also for alkyd coatings, synthetic lubricants, plasticizers, surfactants, rosin esters and the manufacture of explosives. Auxiliaries also directly used for PVC resin and the thermal stability of the alkyd resin applications can enhance the solid resin, color, weatherability, resistance to the chemical nature, sealing.
