摘要:
Alkyl anthranilates are prepared by reacting an isatin with an alkanol and hydrogen peroxide in the presence of an alkali metal alkanolate.The alkyl anthranilates obtainable by the process of the invention are valuable starting materials for the preparation of pesticides, dyes and drugs.
摘要:
Novel bis-anthranilates are obtained by reacting 1 mol of a N,N'-bis-(hydroxyalkyl)-urea with 2 mols of isatoic anhydride. The novel bis-anthranilates are valuable chain extenders for polyurethanes and valuable crosslinking agents for polyurea and epoxide resins.

摘要:
Nitrobenzenes are converted to the corresponding 4-nitroanilines by treatment with hydrogen and hydrogen fluoride in the presence of one or more of certain hydrogenation catalysts, liquid hydrogen fluoride and one or more of certain fluorine-containing acids.
摘要:
The Alpha -monoglycerides of N-( Alpha , Alpha , Alpha trifluoro-m-tolyl)anthranilic acid, N-(2,3-xylyl)anthranilic acid, and N-(2,6-dichloro-m-tolyl)anthranilic acid, useful as pharmacological agents having anti-inflammatory activity, and their production by (a) reacting one of the named anthranilic acids or a carboxylate salt thereof with a 3-halo-1,2propanediol; and (b) reacting a (1,3-dioxolan-4-yl)methyl ester of one of the named anthranilic acids with a strong acid, whereby the dioxolane ring is cleaved.
摘要:
MONONITRO DERIVATIVES OF BENZOIC ACID, AND MONO- AND DICHLORO-BENZOIC ACID, ARE PRODUCED ECONOMICALLY AND IN GOOD YIELD BY NITRATION OF BENZOIC ACID OR CHLORO- OR DICHLORO-BENZOIC ACID ESTERS, PREFERABLY A LOWER ALKYL ESTER, WITH A MIXTURE OF NITRIC ACID AND SULFURIC ACID, OR OLEUM CONTAINING UP TO THE THEORETICAL OF SULFUR TRIOXIDE REQUIRED TO COMBINE WITH THE WATER FORMED IN NITRATION, AT A TEMPERATURE OF ABOUT 10* C, TO ABOUT 80* C. THE THUS PRODUCED MONONITRO ESTERS MAY BE HYDROLYZED TO THE CORRESPONDING MONONITRO-ACID.
