Coper Chlorophylline - Physico-chemical Properties

Molecular Formula	C55H72CuN4O5
Physical and Chemical Properties	Chemical properties dark green viscous substances, can also be blocks, tablets, powder. Slightly ammonia stinks. Good light resistance. Strong deodorization effect. Heating is good fluidity. When the acid is added, the copper is replaced by hydrogen and becomes pheophyllin, and the color turns lighter. Adding alkali is saponified, chlorophyllin and methanol are separated, and become an alkali metal salt of copper chlorophyllin and can be dissolved in water. Soluble in ether, ethanol, n-hexane and petroleum ether. Ethanol insoluble in water and 50%.
Use	Use 1, edible green pigment. 2, mainly used in daily chemical, pharmaceutical, food industry, etc.

Coper Chlorophylline - Production method

extract clover, alfalfa, nettle or dried silkworm manure or tea with acetone aqueous solution or hexane, chloroform, etc. to obtain chlorophyll. Add acetone or methanol, add hydrochloric acid acidified copper chloride methanol solution, heat and stir. After the copper replacement reaction is over, the solvent is distilled, dissolved in hexane, washed with methanol aqueous solution, and then distilled to obtain the finished product. According to FA0/wH0(1 988), the solvent used is limited to acetone, dichloromethane, methanol, ethanol, isopropanol and hexane.
