The yield of Nopol by the heating method reached 64.3%, with SO_4~(2-)/ZrO_2 as the catalyst, calcination temperature 600℃, reaction temperature 120℃for 10h, catalyst amount 4.5%(based on total material weight), and the 1:1.05 molar ratio of paraformal toβ-pinene.
本论文通过大量的单因素与正交实验,提出了合成诺卜醇及乙酸诺卜酯的最佳工艺条件:加热法合成诺卜醇:选用600℃焙烧的SO_4~(2-)╱ZrO_2为催化剂;反应温度120℃;反应时间10h;催化剂用量4.5%(原料总质量);物料配比多聚甲醛:β-蒎烯为(?) 1.05(摩尔比),此条件下诺卜醇得率为64.3%。
