This all big characteristic of L-type, is separated D- types and L-type using crystal seed induction crystallisation；It is obtained second is that first splitting DL- pantoic acid lactones
To D-pantoyl lactone, then reacted with Beta-alanine calcium and D-VB5 calcium is made.The fractionation of DL- pantoic acid lactones generally uses chemical method
Or microbial enzyme method.The shortcomings that chemical method is resolving agent price height, and separation is difficult, and also there are toxicity and problem of environmental pollution.It is micro-
Biological enzyme is the enzyme using high selectivity, and the D- types in DL- pantoic acid lactones are hydrolyzed into Pantothenic acid thus and L-type
It separates.The technique that microbial enzyme method splits DL- pantoic acid lactones has the characteristics that production cost is low, environmentally friendly.
Although the preparation method of calcium pantothenate is able to continuously improve development, the device for preparing calcium pantothenate still needs out
Hair.
