    摘要： The present invention is directed to the preparation of 3-hydroxy diphenylethers and with the use of such 3-hydroxy diphenylethers in the preparation of 3-alkoxy diphenylethers. More particularly, the present invention is concerned with the preparation of 3-hydroxy-4-nitrodiphenylethers and with the use of such 3-hydroxy-4-nitrodiphenylethers in the preparation of 3-alkoxy-4-nitrodiphenylethers. Many of the 3-hydroxy-4-nitrodiphenylethers and the 3-alkoxy-4-nitrodiphenylethers exhibit herbicidal activity.

    摘要： This invention provides a convenient process for the preparation of monoacylhydrazines from carboxylic acids or their salts and hydrazine or substituted hydrazine in the presence of a 1,3,5-triazine substituted with at least one chloro or fluoro. The resulting monoacylhydrazine can further be converted to a diacylhydrazine by effectively either repeating the reaction or through reaction with a carboxylic acid chloride.

    摘要： Crosslinked poly(amino acids) useful as superabsorbent polymers and an improved process for preparing the crosslinked poly(amino acids) is disclosed. Use of polyaziridine and polyepoxide crosslinkers allows the production of superabsorbent polymers that is free of special handling steps required to process hydrogel materials using conventional preparation methods.
