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.
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.
1> Cosmetic Raw Materials: Cosmetics is a variety of raw materials through a reasonable deployment of processing from the compound mixture. Cosmetics with a wide range of raw materials, different performance. According to the Raw Material properties and uses of cosmetics, can be divided into matrix materials and auxiliary raw materials in two categories.
2> Active Pharmaceutical Ingredients(API): API refers to the raw materials in the production of various types of preparations, which is the active ingredient in powder,crystal and paste for medicine use through chemical synthesis,plant extract, and preparations of biotechnology institute.
3> Fragrance And Spices: Spices are an important part of fine chemicals, it is composed of natural spices, synthetic spices and single fragrance.
4> Organic Raw Material: Intermediates are also known as organic intermediates. The use of coal tar or petroleum products as raw materials to produce dyes, resins, additives, and other intermediates.
5> Chemicals Used In Paints: Paint, the traditional Chinese name is paint. So-called coating is coated on the surface of the object that be protected or be adornment, and with the continuous film coating to form strong adhesion.
6> Pharmaceutical Intermediates: The so-called pharmaceutical intermediates, refers to the production of pharmaceutical products in the process, the use of raw materials, materials, accessories and other intermediate products.
