摘要:
A process is claimed for preparing granulated acyloxybenzenesulfonates which consists in granulating a mixture composed essentially of acyloxybenzenesulfonate and optical brightener.
摘要:
A process for preparing acyloxybenzenesulfonates by reacting anhydrous phenolsulfonates with carboxylic acid derivatives comprises conducting the reaction with a salt of a phenolsulfonic acid which has a water content of less than 0.5% by weight and has been contacted with a substance having basic properties.
摘要:
A process for preparing acyloxybenzenesulfonates by reacting a carboxylic acid derivative with a salt of a phenolsulfonic acid in the presence of an antioxidant, preferably 2,6-di-tert-butyl-4-methylphenol. The addition of such antioxidants gives a product having a high color quality.
摘要:
The invention relates to a method for producing bisbenzoxazoles that are interconnected by means of a system of conjugated double bonds, according to which o-aminophenols are reacted with dicarboxylic acids, the carboxyl groups of which are interconnected via a double bond or a system of conjugated double bonds, to form an ammonium salt, said ammonium salt being converted in the presence of dehydrogenating catalysts and solvents with a low dielectric loss into benzoxazol by means of microwave radiation.
摘要:
The invention relates to construction materials, in particular concrete, which contain polyester fibers. The polyester fibers are treated with an oligoester to improve their incorporation into the construction materials.
摘要:
The invention relates to a method for producing tertiary amides of alkylphenyl carboxylic acids by reacting at least one secondary amine with at least one alkylphenyl carboxylic acid to form an ammonium salt, said ammonium salt being subsequently converted into the tertiary amide by means of microwave radiation.

摘要:
The invention relates to a method for producing fatty acid alkanol amides by reacting at least one amine that contains at least one primary or secondary amino group and at least one hydroxyl group with at least one fatty acid to form an ammonium salt, said ammonium salt being subsequently converted into the alkanol amide by means of microwave radiation.
