    Toluene diisocyanate liquid

    Toluene diisocyanate Raw Materials is insoluble in water; soluble in acetone, ethyl acetate and toluene. Reacts easily with compounds containing active hydrogen atoms: amines, water, alcohols, acids, bases, especially with sodium hydroxide and tertiary amines in an uncontrollable way, and gives off a lot of heat. Reaction with water to form carbon dioxide is one of the key reactions in the manufacture of polyurethane foam; should be avoided from moisture.Toluene diisocyanate Raw Materials polymerization reaction speed is very slow at room temperature, but heated to more than 45 ℃ or in the presence of catalysts can be self-polymerization to produce dimers. It can react with strong oxidizer. It will catch fire when exposed to heat, open flame or sparks. Decompose by heating to release cyanide and nitrogen oxides.

    production methodprocess of Toluene diisocyanate liquid

    Toluene diisocyanate liquid is produced by the action of 2,4-diaminotoluene and phosgene, firstly, dissolve solid diaminotoluene in chlorinated benzene, and warm up to 70℃ to get diaminotoluene chlorobenzene solution under stirring, then recycle the oxidized benzene which is photogasified, put it into low temperature phosgene cooker, make up a certain amount of liquid phosgene, and then dropwise add prepared diaminotoluene solution under stirring and carry on photogasification in 40℃, then put it into low temperature phosgene cooker. ℃ for photogasification, and then the low-temperature photogasification of the material into the high-temperature pot for high-temperature photogasification, while heating and venting, about 4h, the reaction is generally carried out at 120 ~ 125 ℃; the reaction is completed, after nitrogen to drive the gas, distillation, distillation and obtained.
