The result shows that catalyst concentration, reaction time, urushiol concentration and temperatures affect the polymer yield in oxypolymerization of urushiol system.
The effects of reactant ratio, reaction time, catalyst amount,the species and amount of deaquation reagent on the yield of benzaldehyde 1,3-butanediol acetal were investigated.
The method of synthesising terpinol with ion exchange resin catalysis was investigated. Effects of kind of solvent used, reaction temperature and reaction time on product output were studied.
