Starting from methyl dehydroabietate, six derivatives of methyl 12-substituted-dehydroabietate were synthesized through several steps, such as bromation, nitration, reduction and diazotization, and the effect of the different groups of methyl 12-substituted-dehydroabietate derivatives on their UV and fluorescence properties was also investigated.

Starting from dehydroabietic acid and methyl dehydroabietate,six aromatic ketones containing rosinyl skeleton were synthesized through Friedel-Crafts acylation,using aluminum chloride anhydrous as catalyst.

In the presence of alkaline soap as emulsifier and catalyst, hydrogenated rosin sucrose esters (HRSE) were synthesized by transesterification reaction of hydrogenated rosin ethyl ester and sucrose under the conditions of (125±1)℃,molar ratio of hydrogenated rosin ethyl ester to sucrose 1 ∶1, pressure 0.

Optimization of technological conditions of synthesize hydrogenated rosin glycerin ester by simplex search method;

The production and application general situation of hydrogenated rosin and hydrogenated rosin glycerin ester was introduced.

Starting from dehydroabietic acid, which was purified from disproportionated rosin, three novel heterocycle compounds, methyl 12,13-oxofurazan-deisopropyldehydroabietate, methyl 12,13-furazan- deisopropyldehydroabietate and methyl 12-bromo-13,14-oxofurazan-deisopropyldehydroabietate were syn- thesized through several steps, such as methylation, bromination, nitration and cyclization.
