Disproportionated potassium rosin ester is a product independently developed by Zibo Pengxin Chemical Technology Co
, Ltd
, which implements the enterprise standard
This product adopts solar heating low-temperature reaction technology
After rosin disproportionation reaction, it is the product generated by esterification with alcohol and carboxylic acid
The disproportioned potassium rosin ester maintains an amber transparent oily liquid with 50% effective content
Through esterification reaction, it eliminates the conjugated double bond system, improves the polymerization rate of synthetic rubber and resin, effectively reduces the cost and reduces environmental pollution
This product is mainly used as an emulsifier to participate in the lotion polymerization and emulsification reaction of styrene butadiene, neoprene, nitrile, high benzene and other synthetic rubber and ABS synthetic resin
In the polymerization reaction, the monomer particles dispersed in water with emulsifier are stable colloidal system

This product is different from disproportioned rosin acid potassium soap
At present, the domestic production of disproportioned rosin acid potassium soap is mainly the saponification reaction of disproportioned rosin and potassium hydroxide alkali solution
The product is dark in color and there are widespread gel and crystallization phenomena, which seriously affects the speed and effect of lotion polymerization in rubber production
Disproportioned potassium rosin ester is an oily liquid with amber color and high transparency when the effective content is 50%, which is convenient for use, packaging and transportation

Disproportionated rosin is the product obtained by the disproportionation reaction in which one part of rosin is oxidized and the other part is reduced in the presence of catalyst
The disproportionation reaction enables the molecular rearrangement of abietic resin acids through hydrogen transfer and eliminates the conjugated double bond system
All rosin acids with conjugated double bond structure have the effect of inhibiting the polymerization of synthetic rubber and resin, resulting in the decrease of polymerization rate
The reason is that the free radicals produced by the redox reaction system can initiate polymerization only when they enter the micelles formed by the emulsifier or the monomer polymer latex particles protected by the emulsifier
The existence of conjugated double bonds in the emulsifier components consumes a large number of free radicals, resulting in the inability of polymerization, which is reflected in the reduction of polymerization rate in production
