补充资料:多苯基多次甲基多异氰酸酯
分子式:C6H4(NCO)CH2C6H4(NCO)C8H5NO)X
分子量:350-400
CAS号:9016-87-9
性质:褐色透明液体。相对密度为1.200,折光率1.6240。蒸气压(25℃)为2.13×10-5kPa。
制备方法:将苯胺和甲醛按摩尔比1.6-2.0:1配合,再配入盐酸作为缩作催化剂,加入缩合器中,于90-110℃反应30-60min,得到一定比例二苯基甲烷-4,4'-二胺和多次甲基多苯基甲胺,再经光气化、分离、提纯即可得PAPI和MDI。原料消耗定额:甲醛(100%)150kg/t、苯胺750kg/t、光气850kg/t。
用途:用于制聚氨酯材料,广泛应物于建筑行业、汽车工业、电器工业等作保温材料或垫褥等。
