Production method
1. Shunyu direct catalytic hydrogenation method Shunyu in the presence of argon-alumina (or copper tantalum) catalyst, at 160 degrees C, 5.8MPa hydrogenation can produce butyl diacid. The conversion rate was 98.8%. The selectivity of butyl glyphosate is 100%.
2. Butyl diacid dehydrated fabutyric acid heating to more than 260 degrees C, or add a certain amount of tetrahydroquine and toluene, while heating to more than 200 degrees C, can be dehydrated to produce butyl diacid. The content and yield of butyl glycerine were about 90%. The dehydration process of butyl acid can also be carried out in the presence of dehydration agents acetyl, phosphorus pentaoxide, dichlorooxyphosphate, etc. For example, the butadiic acid and triclosan phosphorus are heated back into the stream, the hydrogen chloride gas is exhausted, and then decompression distillation, the collection of 160-165 degrees C (5.33 kPa) fractions, cooled to a white block of butyl acid.
