Abstract
The invention discloses a synthesizing method and application of 5, 6-epoxy-beta-ionone based on cupric phosphate hydroxyl as catalyst, which is characterized by the following: adopting the molar rate of raw material and catalyst at 0.01-50%; heating to 40-150 deg.c; oxidizing beta-ionone through oxygen or air to obtain the product.
Description
Technical field
The present invention relates to hydroxyl cupric phosphate and synthesizing 5, the application in the 6-epoxy-bata-ionone, and synthesize 5, the method for 6-epoxy-bata-ionone.
Background technology
5, the systematic naming method of 6-epoxy-bata-ionone is: " 3-buten-2-one, 4-{2,2,6-trimethyl-7-oxabicyclo (4.1.0) hept-1-yl}-".This compound is the important spices of a class, in particular as tobacco aromatics using, various cigarette is had significant perfuming effect.Along with smoking and health problem are subject to people's attention day by day, fall that smoke that Jiao causes is thin must to need synthetic tobacco aromatics using to remedy.The epoxidation Reaction of Alkenes method is a lot, molecular oxygen is because oxidation products is a water, pollution-free and economy is easy to get and is described as " green oxygen source ", contains chromium cpd and oxymuriate or hypochlorite oxidizing reaction relatively with general, and molecular oxygen or atmospheric oxidation have environment-friendly advantage clearly.Which kind of catalyst activation molecular oxygen is the key of molecular oxygen oxidation be to adopt, and makes it to interact with alkene.Conclusion is got up, and the oxide catalyst of alkene is divided into homogeneous catalytic reaction system and heterogeneous catalytic reaction system.The former comprises some metalloporphyrin classes, metal phthalocyanine class, Schiff bases, picolinamide Base Metal title complex etc., and heterogeneous catalyst comprises polymer carrier loading type, inorganic carrier catalyst catalyzer, heteropolyacid salt type catalyzer etc.These catalyzer otherwise be difficult to the preparation, the cost height as the metalloporphyrin class, or exists selectivity not high, by product is many, perhaps reclaims problems such as difficulty.
Summary of the invention
The objective of the invention is to hydroxyl cupric phosphate is applied to as catalyzer synthetic 5, in the 6-epoxy-bata-ionone, can make synthetic method have environmental protection, reaction is efficient, convenience operation.
Another object of the present invention is to provide a kind of and synthesize 5,6-epoxy-bata-ionone method.
The objective of the invention is to realize by following manner:
The present invention is used for hydroxyl cupric phosphate to synthesize 5, the 6-epoxy-bata-ionone as catalyzer first.
The present invention is used for the oxidizing reaction of catalysis alpha, beta-lonone with hydroxyl cupric phosphate, and reacted hydroxyl cupric phosphate can reclaim use again after filtering, cleaning.Hydroxyl cupric phosphate wherein also is named as the copper based phosphates, or alkali formula cupric phosphate, and chemical formula is Cu
2(OH) PO
4By the special Application of Catalyst of the present invention, make and synthesize 5,6-epoxy-bata-ionone method has environmental protection, efficient, convenience operation.
The catalyzer that uses among the present invention can obtain hydroxyl phosphoric acid ketone by the following method, certainly also can be according to other synthetic method preparation.Can also with the hydroxyl cupric phosphate of natural generation catalyzer.

The present invention is synthetic 5, and 6-epoxy-bata-ionone method is: will be equivalent to the alpha, beta-lonone mol ratio and be 0.01%～50% hydroxyl cupric phosphate and join in the alpha, beta-lonone, be under 40～150 ℃ in Heating temperature, aerating oxygen or air.The GC-MS detection reaction is carried out degree, and is complete up to feedstock conversion.Filter, and clean recyclable catalyzer.
The employed oxygenant of oxidation alpha, beta-lonone is oxygen or air among the present invention.The Heating temperature scope of catalyzed oxidation is 40～150 ℃, and wherein preferred Heating temperature is 60～90 ℃.Reaction temperature is spent low, and then speed of response is slow.But temperature of reaction is too high, and by product is many, and product selectivity reduces.Catalyzer hydroxyl cupric phosphate better catalytic activity, the catalytic amount of 1.7% (with respect to the amount of raw material) just has reasonable catalytic effect.Though the increase of catalytic amount can increase the speed of oxidizing reaction, from cost consideration, the preferred amount ranges of catalyzer is for being equivalent to alpha, beta-lonone amount of substance 0.5%～10%.
The catalytic oxidation raw material is an alpha, beta-lonone, and structural formula is seen formula 1.
