【摘要】 对碳酸二甲酯与己二胺甲氧羰基化反应的产品1,6-六亚甲基二氨基甲酸甲酯进行了定性分析,考察了催化剂用量、原料配比、反应时间和溶剂等操作条件对反应过程的影响。催化剂为CH3CONa或CaCl2;较好的反应条件为:n(催化剂)∶n(己二胺)=0.01∶1,n(碳酸二甲酯)∶n(己二胺)=5∶1,反应时间20h。更多还原

【Abstract】 Dimethylhexane-1,6-dicarbamate is qualitatively analysed which is synthesized by dimethyl carbonate with 1,6-hexane diamine. The effects of dosage of catalyst,mole ratio of DMC to HAD,reaction time,solvent etc on the reaction are studied. When using CH3CONa,CaCl2 as catalyst;the optimal reation conditions are as follows:n(cat)∶n(HAD)=0.01∶1,n(dimethyl carbonate)∶n(amine)=1∶5,reaction time 20 h.更多还原
