摘　　要：报道了双波段紫外光照射 7 脱氢胆甾醇合成维生素D3的放大实验研究 ,发现它与激光两步照射合成法产物随时间变化曲线非常相似 ,维生素D3的前身P3的转化率约为 61 % 。The experimental research for synthesizing of Vitamin D 3 was made by irradiating 7 dehyocholesterol (7 DHC) with two stage ultraviolet light,which is mercury lamp with two kinds of solution filtrating.This paper compares the yield of previtamin D 3(P 3) of irradiating 7 DHC by two stage ultraviolet light with by laser at 254nm and then 350nm.The ultimate rate of previtamin D 3(P 3) is about 61%,which is higher than the yield of traditional mercury lamp irradiating continuously.
