【Abstract】 The optimun technological conditions were studied on the synthesis of 9-flourenylmethanal by the reaction of flouren and ethyl formate , and the synthesis of 9-flourenylmethanol by the reaction of 9-flourenylmethanal and methanal with sodium ethylate as catalyst. The results showed that the yield of 9-flourenylmethanal was over 75%, when flouren was 16g ,the amount of catalyst was 4.5g, the amount of ethyl formate was 66mL,and the reaction time was 36h, and showed that the yield of 9-flourenylmethnol was over 63%, when 9-flouernylmethanal was 19g,the amount of methanal was 7.0ml, 10% NaOH solution was 70ml, and the reaction time was 2.0h.
【Key words】 flouren; 9-flouernylmethanol; sodium ethylate; catalytic synthesis;
