| titleOfInvention | A kind of artificial synthesis of Natural Curcumin class thing |
| abstract | The present invention relates to Natural Curcumin class thing technical field, particularly a kind of artificial synthesis of Natural Curcumin class thing.The artificial synthesis of this Natural Curcumin class thing, its special character is: by methyl ethyl diketone with diluted ethyl acetate, stirring reaction is carried out with under boron trioxide room temperature, obtain methyl ethyl diketone-boron trioxide solution, another by benzaldehyde derivative with diluted ethyl acetate, add dewatering agent, then after mixing with above-mentioned methyl ethyl diketone-boron trioxide solution, add catalyzer, stirred at ambient temperature reacts, and is poured into by reaction solution in frozen water, isolates organic layer, recrystallization after being concentrated, obtains curcumin.The invention has the beneficial effects as follows: simple to operate, reaction conditions and easy temperature control, raw material is easy to get, and purity is high, and it is higher than 98%. |
