And pulping procedures influenced the structural features of residual lignin of pulps including the content of aliphatic and phenolic hydroxyl groups, β_O_4 structures, carboxylic acid groups, and condensed lignin units. 制浆方法影响纸浆残余木素的结构特征,包括脂肪羟基、酚羟基和羧基含量,βO4结构和缩合结构含量。
The N-acac-amino acid-Cu system oxidized not only the sec-alcohols of benzylic and aliphatic alcohols to corresponding ketones, but also the primary alcohol to the corresponding carboxylic acid. 乙酰丙酮-亮氨酸-铜体系不仅能够将脂肪醇和芳香醇的仲醇氧化成相应的酮,而且也能将伯醇全部氧化成相应的羧酸。
