Secondly diisothiocyanates were synthesized by the phase transfer reaction of bischloroformate and potassiumthiocyanate;
然后将双氯甲酸酯与硫氰酸钾在相转移催化剂的催化下反应生成二异硫氰酸酯；
2
The treatment process of liquid waste in synthesis of cuprous thiocyanate by use of sulfocyanide ion existed in the liquid waste of potassium rhodanate was investigated.
