研究了α,α-二苯基-4-吡啶甲醇的催化加氢工艺,考察了反应温度、压力、溶剂和不同催化剂对催化加氢的影响,发现在反应过程中加入少量溶剂助剂能显著地缩短反应时间、降低反应温度和压力,并且产物不需要浓缩即可结晶分离,α,α-二苯基-4-哌啶甲醇的收率93.0%,产品纯度≧99.3%.

This paper studied on technics of catalytic gydrogenation of α,α-dipheny 1-4-pyridinemethanol, the effects of temperature, pressure, solvents, reacting time and catalyst on the yield were inrestigated. Using assistant solvents Y-1, temperature and pressure were depressed, reacting time it can be reduced. The product will be separated without condense and crystal,the result showed that the yie...
