Abstract

Tertiary rosin alcohols are prepared by reacting an ester of a substituted or unsubstituted abietic, dehydroabietic, l- or d-pimaric acid with a Grignard reagent and hydrolysing the product. In examples: (1) dimethyl-tert-dehydroabietinol is prepared from methyl dehydroabietate and methyl magnesium iodide; (2) diphenyl-tert-dehydroabietinol is prepared from methyl dehydroabietate and phenyl magnesium bromide; (3) diphenyl-tert-dehydroabietinol is prepared from ethyl dehydroabietate and phenyl magnesium bromide; (4) diphenyl-tert-abietinol is prepared from methyl abietate and phenyl magnesium bromide; and (5) diphenyl-tert-6-hydroxydehydroabietinol is prepared from methyl 6-methoxydehydroabietate and phenyl magnesium bromide. The Specification as open to inspection under Sect. 91 comprises also the use of other acids obtained by the hydrogenation, disproportionation and isomerization of primary rosin acids. This subject-matter does not appear in the Specification as accepted.
