N-methylpyrrolidone is referred to as NMP, molecular formula: C5H9NO, English: 1-Methyl-2-pyrrolidinone, the look is colorless to mild yellow obvious liquid, barely with the odor of ammonia, miscible with water in any proportion, soluble in ether, acetone and ester, haloalkane, fragrant hydrocarbon and different natural solvents, nearly totally combined with all solvents, boiling factor 204 ℃, flash factor ninety one ℃, sturdy hygroscopicity, steady chemic

Polyvinylpyrrolidone, additionally recognised as PVP, is a polymer of ethylene pyrrolidone. Due to its one-of-a-kind ranges of polymerization, it can be divided into soluble PVP and insoluble PVPP (polyvinylpyrrolidone). The relative molecular weight of soluble PVP is 8000~10000, which can be used as a precipitant to precipitate with the aid of reacting with polyphenols. By the use of this method, there are without problems residual PVP in the wine.

Coconut oil is recognized as the "healthiest oil on Earth". Coconut oil, as a medium chain fatty acid, has drastically special physiological consequences on the human physique in contrast to the often discovered lengthy chain fatty acids in our food. The saturated fatty acids in coconut oil are on the whole medium chain fatty acids.

Nickel chloride can take part in the response as a moderate Lewis acid, catalyze the coupling reaction, and coordinate with metallic hydride as a lowering agent to take part in the selective discount reaction. As a moderate Lewis acid, nickel chloride can realise the regioselectivity rearrangement of dienols in alcohol water solution.
