本标准规定了工业用对苯二酚的技术要求、试验方法、检验规则及标志、包装、运输、贮存和安全。 本标准适用于苯酚羟基化法或苯胺法制得的工业用对苯二酚的生产、检验和销售。结构式、分子式略
Hydroquinone for industrial use
本部分规定了用容量法和紫外分光光度法测定工业用乙酸乙烯酯中对苯二酚含量的方法。本部分适用于测定对苯二酚的含量为(1~20) mg/kg的工业用乙酸乙烯酯。由于试样中存在的醛、酮类化合物在295 nm也会有紫外吸收,当采用紫外分光光度法测定时,将使测定结果偏高
Vinyl acetate for industrial use.Part 6: Determination of hydroquinone
本标准规定了工业用邻苯二酚的要求、试验方法、检验规则、标志、包装、运输、贮存和安全。 本标准适用于以苯酚羟基化法制得的工业用邻苯二酚的生产、检验和销售。 结构式、分子式略
Catechol for industrial use
PHENOL, o - CRESOL, m - CRESOL, p - CRESOL, CRESYLIC ACID AND XYLENOLS FOR INDUSTRIAL USE DETERMINATION OF VVATER BY THE KARL FISCHER METHOD
