表面活性剂对N,N′-二苯基硫脲合成的影响研究 |
许保恩(石家庄高等师范专科学校化学系; 河北石家庄) |
摘 要:对原N,N′ 二苯基硫脲的合成方法进行改进,考察不同种类表面活性剂在单用和复配时对反应的影响,找到较好的活性剂配伍,使反应时间由原来的6h减少到3h,CS2加入量由原来的过量100%降低为过量40%。 |

The Affection of Surface Active Agents on the Synthesis of N,N′-Diphenlthiourea |
XU Bao-en (Shijiazhuang Teachers College; Shijiazhuang 050801; China) |
Abstract:The orignial synthetic method was improved. The affection of different kinds of surface active agent on the reaction was inspected, therefore, a better complex of active agents was chosen. The reaction period is less 3 hours than that of primary technology and the quantity of CS_2 is decreased by 60%. |
Key words:N; N′-diphenlthiourea; synthesis; surface active agent; affection |
