What is Phenethyl Acetate?

Phenylethyl acetate is a colorless liquid; a rose-like floral aroma with a honey-like undertone, a sweet fruit-like taste like strawberries; steaming factor 232 ° C; flash point 105 ° C; thickness D25251.030 ~ 1.034; Refractive index nD201.4970 ~ 1.5010; acid value not surpassing 1; soluble in 70% ethanol at 1:2 or above, soluble in a lot of common organic solvents. Phenylethyl acetate is a typically made use of artificial fragrance. It has actually been commonly used in the preparation of rose, orange blossom, violet, wild climbed and fruity fragrances.

Phenethyl Acetate Uses

Phenylethyl acetate can be used in the prep work of commode soap and also day-to-day cosmetic significance, and also can be made use of as a substitute for methyl heptynoate. It is commonly used in the deployment of rose, orange blossom, wild climbed as well as various other essences, along with fruit significances (with peach fragrance).

1) Prepare a sort of honey taste of natural taste of honey, which is composed of linalool oxide, glycerol triacetate, ethanol, propylene glycol, phenylethyl alcohol, turkenone, ethyl maltol, as well as honey scent base, as well as the honey fragrance base is turkene Ketone, Rose Geranium Oil, 4-Hydroxy-2,5-Dimethyl-3(2H)furanone, Triethyl Citrate, Methyl Anthranilate, Vanillin, Caproic Acid, Nonanoic Acid, 2 – Structure of acetylfuran, 2-methylbutyric acid, α-terpineol, butyric acid, benzaldehyde, phenylethyl phenylacetate, phenylethyl acetate, phenylethyl butyrate, propylene glycol, propylene glycol and ethyl The base maltol is combined as well as heated to dissolve, then cooled to area temperature, as well as triacetin, ethanol, linalool oxide, phenylethyl alcohol, turkelenone, as well as honey scent base are included in get the product. The honey essence has a good honey-sweet taste.

2) Prepare a coffee bean elephant attractant. Coffee bean elephant attractants consist of benzyl alcohol, 2-phenylethyl alcohol, benzyl acetate, and also phenylethyl acetate. The weight percent of each component in the coffee bean elephant attractant consists of: benzyl alcohol-3-15-%, 2-phenylethyl alcohol-30-42-%, benzyl acetate-15-20-%, phenylethyl acetate -32 -43-%. A lot of the attractant components of the here and now innovation are second metabolites of bacteria, easy in structure, broad in resource, economical in price, straightforward as well as practical in manufacturing technique of appeal core, simple in use technique, low in labor strength, and the catch consisting of attraction core can be straight put on hold as well as put on Above the kept items, it is incredibly suitable for parasite control in the storage environment.

The Preparation Method of Phenylethyl Acetate

A sort of artificial approach of phenethyl acetate is characterized because the approach may additionally make up the steps:
Step 1. Include 100g of phenylethyl alcohol, 200ml of dichloroethane, and also 2g of stimulant Pt/Si02g into a 500ml four-neck flask geared up with a mechanical mixing rod, a reflux condenser, as well as a consistent stress funnel, and also gradually add 55g of acetic anhydride dropwise under stirring to raise the temperature as well as reflux for 1h;

Step 2, transform the reflux tool right into a distillation gadget, and distill part of dichloroethane up until the distillate is clear, and the distilled quantity is 100ml;

Step 3. Trendy the reaction fluid to listed below 10 ° C, laundry with ice water to get a dichloroethane service of phenylethyl acetate, completely dry over anhydrous magnesium sulfate, as well as distill off dichloroethane completely by vacuum cleaner purification to acquire phenylethyl acetate ester.

Described Pt/SiO catalyst prep work technique is as adheres to:
Action 1. Completely dissolve 3g NaSiO 9H0 and spread it in water, after that slowly include 10g of ethyl acetate dropwise, and also keep mixing for 1h to finish the response;

Action 2. Place the above solution in the air to age for 24 hr, filter, wash with water two times, and also completely dry in vacuum at 40 ° C for 6 hrs to get SiO nanoparticles;

Action 3. Disperse 2 mg of Si0 in 5 mL of water, add 1 wt % hydrofluoric acid to engrave for 1 min, after that add 1.33 ml of 38.62 mM HPtCl, as well as oscillate ultrasonically for 30 minutes;

Step 4. Include 3ml of 40mM NaBH reducing agent to the above mixture, continue ultrasonic oscillation for 2h up until the remaining NaBH is fully decayed, and after that centrifuge and also wash until PH= 7;

Tip 5. Put the centrifuged item above into a vacuum drying out oven at 40 ° C., and completely dry it for 8 hours to acquire a Pt/Si0 nanometer driver.

The Synthetic Method of Phenylethyl Acetate

Phenylethyl acetate can be extracted from natural vegetable oils. Because phenylethyl acetate naturally exists in white orchid oil and rose oil, the composition is complex, and when it is extracted from natural vegetable oils, there is a problem that it is relatively difficult to separate.

It can also be synthesized by esterification. Phenylethyl acetate can be obtained by esterification reaction of acetic acid, acetic anhydride and phenylethyl alcohol in the presence of a catalyst.

Because the price of the raw material phenylethanol used in the synthesis of esterification is relatively high, the price of acetic anhydride is also high and the state control is very strict, while the price of acetic acid is relatively low, so the synthetic route of reaction between acetic acid and phenylethanol is mostly used in production. That is to use acetic acid and phenylethyl alcohol to heat and reflux for several hours under the action of a catalyst. After the reaction is completed, it is obtained by cooling, washing with water, neutralizing, washing with water until neutral, drying and distilling under reduced pressure. Because esterification is a reversible reaction and the yield is not high, it is usually used to increase the yield by using excess acetic acid in the reaction. After the reaction is completed, acidic wastewater will be generated, which is likely to cause environmental problems. It must be discharged after neutralization, and a large amount of waste water will be consumed. Alkali will cause waste of resources.

CN103553914A discloses a kind of synthetic method of phenylethyl acetate, is characterized in that comprising following process steps:

1>In the reaction kettle, add catalyst and ethyl acetoacetate, stir and heat to reflux, add benzyl chloride dropwise, and react under reflux for 2-6 hours to generate ethyl benzyl acetoacetate, evaporate the solvent and cool to room temperature, add water Stir to dissolve, add acid to adjust pH to 7, let stand to separate the layers, separate the oily substance in the lower layer, wash with water to obtain ethyl benzyl acetoacetate;

2> Add catalyst to the above product, reflux reaction for 2-6 hours, oily matter is formed, cool to below 30°C, add acid to adjust to PH = 1-2, continue heating and reflux for 1-4 hours, steam at normal pressure to remove low boiling Thing, obtains crude product benzyl acetone, distills under reduced pressure, obtains refined benzyl acetone;

3> Add refined benzyl acetone, m-chloroperoxybenzoic acid and solvent into the reaction kettle, react at room temperature for 2-6 hours, adjust the pH to 7 with alkali, separate the oil, wash with water, distill off the solvent, and refine acetic acid Phenylethyl ester, add acid to the water layer to adjust to PH = 1-2, crystallize, filter and recover m-chlorobenzoic acid, and the recovered m-chlorobenzoic acid is recycled.
