螺旋藻制取叶绿素铜钠盐

用乙醇提取螺旋藻中的叶绿素，再用５％ＮａＯＨ溶液皂化、石油醚萃取，在酸性环境中用１０％ＣｕＳＯ４溶液实现铜镁置换，沉淀物经丙配溶解后，加２％ＮａＯＨ的乙醇溶液成盐，过滤，水洗，真空干燥，制成叶绿素铜钠盐．制品的质量达到ＧＢ３２６２－８２的要求．提取率为６４．７％，制品得率占藻粉１．１％。着重对铜镁置换的条件、制品耐酸、耐热、耐光等性能进行了对比试验，结果表明整个工艺是切实可行的．

The Study on Making Sodium Copper Chlorophyllin by Spirulina

Extracting Chlorophyll from Spirulina by using ethyl alcohol and the making of SodiumCopper Chlorophyllin is studied in this paper. The technological process is saponifying with 5%NaOH solution, extracting with petroleum ether acidification reacing with 10% CuSO4 solution.The dissolving of sedimentary deposits with acetone, in whith alcohol solution with NaOH(2% )is added, performing the processes of salt-forming, filtering, washing, vaccum drying in turn,then the product Sodium Copper Chlorophyllin will be obtained. The product quality is up to thestandard of P. R. O. C Sodium Copper Chlorophyllin GB3262-82. Its extraction rate is 64. 7% andits obtaining rate from Spirulina powder is 1. 1%. The comparitive experiments of the optimumcondition of extracting chlorophyll from Spirulina and replacing Mg2 with Cu2 , acid enduranceheat endurance and light endurance of the product have also been done. The result of the studyshows that the whole technology is practicable.
