摘要:
Alkyl substituted or unsubstituted, bicyclic keto acids may be prepared by cyclizing unsaturated, cyclic dicarboxylic acid anhydrides in the presence of a strong Bronsted acid catalyst. The products may be useful as corrosion inhibitors in alcohol fuels and as intermediates in petroleum, pharmaceutical and additive manufacture.
摘要:
A keto-acid amide derived from the amination of a bicyclic keto-acid with an N-alkyl-alkylene diamine. The keto-acid amides are useful as carburetor detergents for motor fuel compositions.
摘要:
Novel condensation products of N-alkyl-alkylenediamines and isopropylidene malonate are prepared by refluxing the reactants in solvents inert to the reactants, removing this solvent and extracting the reaction system with an inert solvent such as xylene.
