Background technology
Dimeric dibasic acid, is often referred to dimer (fatty acid) yl, is the mixture of a kind of complicated component, because main component contains
Two hydroxy-acid groups and gain the name.It is to use unsaturated fatty acid, if oleic acid and linoleic acid are by mutual polymerization etc.
Obtain.Dimeric dibasic acid has excellent heat stability, and can keep mobility within the scope of the widest temperature.
Dimeric dibasic acid is currently mainly used as synthesizing polyamides, and there are about half in the neutral polyamide synthesized and be used to preparation
PUR, secondly for the production of ink.
The domestic method preparing dimeric dibasic acid is clay catalytic method, and the method is existing two kinds of techniques: one is fat
Fatty acid methyl esters method, with various fatty acid methyl esters as raw material, montmorillenite is catalyst, with methanol deoxygenation.
This technique advantage be equipment be simple and convenient to operate, product quality preferable.But catalyst amount is relatively big,
The purity requirement of methanol is higher.Another kind is fatty acid direct polymerization technique, and employing vegetable oil acid is raw material,
In the case of nitrogen charging, after having reacted, decolour, filter, prepare rough dimeric dibasic acid, then steamed by thin film
Send out in device and distill, obtain smart dimeric dibasic acid finished product.This process recovery ratio is high, steady quality, for domestic current production two
The main technique of polyacids.
At present, essence dimeric dibasic acid is some deficiency below existence when producing: one, and centrifugal separating device is the most only
