["Тер-метилсодержание в терефталевом аппарате丁同-甲苯含量测定", "Задам вопрос大家：： Как измеряется тер-метилсодержание в терефталевом аппарате, 在溶剂中的丁同-甲苯含量是怎么测定的？我在实验室进行同苯脱蜡试验中想测定回收溶剂中丁同-甲苯含量，但是因为在实验室进行的是快速蒸馏，溶剂中颜色发黄，估计是在蒸馏过程中夹带了油品（减算定），不敢直接进色谱柱进行测量，想知道有什么好的办法能够测量其中丁同-甲苯的含量吗？", "СБольшое спасия за ваше бескорыстное поделение！！！！！"
