标题:Method for the synthesis of quaternary ammonium salts
发明人：NAKANO SHINJI; MORIMOTO TAKAO; ENDO TAKESHI
权利人:NIPPON PAINT CO LTD
摘要:Provided is a convenient method for the synthesis of quaternary ammonium sulfonate compounds which are useful as curing catalysts for one-part thermosetting resin compositions which maintain storage stability at room temperature. The compounds are synthesized by subjecting in one step a benzyl alcohol optionally having on the benzene ring and/or the α-position one or more substituent groups to reaction with a corresponding tertiary amine and an organic sulfonic acid chloride.

标 题:Adhesive complex coacervates and methods of making and using thereof
发明人：STEWART RUSSELL J
权利人:STEWART RUSSELL J; UNIV UTAH RES FOUND
摘要:Described herein is the synthesis of adhesive complex coacervates and their use thereof. The adhesive complex coacervates are produced by reacting (a) at least one poly anion comprising a plurality of activated ester groups, and (b) at least one polycation comprising a plurality of nucleophilic groups, wherein the nucleophilic groups react with the activated ester groups to produce a new oovalent bond between the polycation and the polyanion. The adhesive complex coacervates described herein have low interfacial tension with water and wettable substrates. When applied to a wet substrate they spread over the interface rather than beading up. The adhesive complex coacervates have numerous biological applications as bioadhesives and drug delivery devices. In particular, the adhesive complex coacervates described herein are particularly useful in wet or underwater applications and situations where water is present such as, for example, physiological conditions.

摘要:A process for the preparation of an α-ketocarboxylic acid N-tert.-butylamide of the formula n n R--CO--CO--NH--C(CH.sub.3).sub.3 n n in which n R is an aliphatic radical with up to 8 carbon atoms, a cycloalkyl radical with 3 to 6 carbon atoms, a phenyl or naphthyl radical or a heterocyclic radical, n comprising reacting an acyl cyanide of the formula n n R--CO--CN n n with tert.-butyl methyl ether of the formula n n (CH.sub.3).sub.3 C--O--CH.sub.3 n n at a temperature between about 0° and 80° C. in the presence of an acid which is capable of activating the ether of formula (III) under the reaction conditions to give a tert.-butyl carbonium ion, and then hydrolyzing the reaction mixture. Advantageously the acyl cyanide is pivaloyl cyanide or benzoyl cyanide and is reacted with an approximately equimolar amount of the ether in the presence of about 1.1 to 1.5 times the molar amount of concentrated sulphuric acid as the activating acid. The products are useful as intermediates in the synthesis of known herbicides.

标题 :Manufacture of 3-halosulfonylthiophene-carboxylic acid compounds
发明人：ROSSY PHILLIP A; HOFFMANN WERNER; MUELLER NORBERT
权利人:BASF AG
摘要:3-Halosulfonylthiophene-carboxylic acid compounds are manufactured by reacting 3-ketothiophane-carboxylic acid compounds with sulfonic acid compounds, reacting the end product from the 1st reaction stage with alkali metal polysulfides, reacting the end product from the 2nd stage with a dehydrogenating agent and finally reacting the end product from the 3rd stage with halogen and water. The products are starting compounds for the manufacture of drugs, dyes and crop protection agents and have an anti-inflammatory, analgesic and anti-rheumatic action. In particular, the end products I are starting materials for the manufacture of sweeteners which are non-toxic and free from an after-taste, flavor-improving agents, diabetic aids and feedstuffs, and provide the means of a simple and economical synthesis of thiophene-saccharins.
