Abstract

The invention discloses a method for producing a cosmetic perfume. The method comprises the following steps: uniformly mixing cyclohexanone, 1, 3-propylene glycol and a catalyst, adding the mixture into a reaction kettle, centrifugally separating out the catalyst after the reaction is finished, sequentially washing the obtained organic phase with water and saturated salt water until the organic phase is neutral, drying the organic phase with anhydrous magnesium sulfate, and then carrying out refined vacuum distillation operation to obtain a 1, 3-propylene glycol ketal finished product; the catalyst is prepared by combining solid superacid SO4 < 2-> / SnO2-ZrO2 and an acidic ionic liquid, the mass fraction of the solid superacid in the catalyst is 50 wt%-80 wt%, and concretely, the catalyst is prepared by preparation of mesoporous SnO2-ZrO2, preparation of the solid superacid SO4 < 2-> / SnO2-ZrO2 and compounding of the solid superacid SO4 < 2-> / SnO2-ZrO2 and the acidic ionic liquid. The catalyst prepared by the invention not only can overcome the defect that the catalytic activity is greatly reduced due to easy loss of acidity, but also can inhibit the corrosion of the catalyst to reaction equipment and the occurrence of side reaction to a great extent.

Description

Technical field[0001]The present invention belongs to the field of daily chemical technology, and it is related to the production techniques of the perfume of daily cosmetics, and in particular to a production method of cosmetic perfume cyclohexanone-1,3-propylene glycol.Background technique[0002]The fragrance consists of two parts: natural fragrance and synthetic fragrance. Synthetic fragrances are stable, and the price fluctuations are small, the production is not limited by climate and natural environment, so that the advantages of stable supply can be guaranteed, which has been widely used in the day. Use cosmetics, skin care products and foods. Since natural fragrance plants are often limited by factors such as natural conditions, the number of varieties and the product quality are affected. Because the synthetic fragrance is not limited by the natural conditions, the quality is stable, the size of the production scale can be arranged by people, and the price of the product is ...
