Product Description
Description
Phthalic anhydride as raw materials to produce phthalimide more ways, the actual application of industrial production of ammonium bicarbonate and urea method.
1. Ammonium bicarbonate method Phthalic anhydride and ammonium bicarbonate at a molar ratio of 1: 1.2 were mixed, crushed by the crusher into the reactor, heated to about 4h heated to 200 ℃, and then slightly faster speed to 280-300 ℃. The melt out to the crystallization, cooling and solidification, smashing the finished product yield of 95% or more. Phthalimide with a content of 95% per ton consumes 1030 kg of phthalic anhydride and 660 kg of 95% ammonium bicarbonate.
Urea method
This product is an intermediate of many fine chemicals such as side-dye, pesticide, medicine and rubber auxiliary, for example, used for producing phthalide, phthalonitrile, indigo, sterilizing agent sterilant, insecticide, and many more.
