    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.
