What is Styrax?

Styrax and also phenylethyl alcohol are isomers, additionally called α-phenylethyl alcohol. These two substances have different frameworks and physical and chemical buildings, as well as are additionally various in scent. Su Hanxiang is smooth like a vibrator flower, and also has a purple-like aroma, while phenylethyl alcohol is generally a rose-like fragrance.Phenylethyl alcohol naturally exists in plant essential oils such as roses, bay leaves, and sandalwood, and there is no report of Styrax existing in nature. Stella alcohol is widely used in daily chemical and cosmetic industries, dyes, medicines, preservatives and other industries.

At present, large-scale industrial production adopts organic synthesis method to use acetophenone as raw material, and hydrogenation and reduction produce α-phenylethanol. Use lithium aluminum tetrahydride, sodium borohydride or aluminum isopropoxide as a catalyst to prepare phenylethyl alcohol by hydrogenation and reduction of acetophenone, but the reaction conditions are harsh and need to be carried out in an anhydrous environment, and the reaction system is homogeneous, and the product and reduction It is difficult to separate the catalysts and catalysts, the post-processing of the products is troublesome, and it is easy to cause environmental pollution. The method of heterogeneous catalytic hydrogenation can realize the effective separation of products.

The conventional method is to use hydrogen as the hydrogen source and use supported noble metals (Pt, Ru, Pd) as the catalyst to synthesize. The selectivity of the C=O reduction reaction is low, and a large amount of by-products of benzene are brought, and the reaction conditions are relatively harsh, the catalyst is expensive, and the production cost is high. In addition, alcohols are used as hydrogen sources to prepare corresponding alcohols by hydrogenation and reduction of ketones or aldehydes. The reaction conditions are mild, and the reaction temperature is generally the boiling point of the corresponding alcohols, which can be carried out under normal pressure. The catalyst used in the reaction generally only carries out the addition reaction to the carbonyl group, and has no effect on other unsaturated groups, has high selectivity, and has no by-products after the reaction.

Application of Styrax

Styrax is an essential fragrance and also great chemical intermediate, which is extensively utilized in medicine, fragrance production, cosmetics, food and also great chemical sectors because of its special physical and chemical residential or commercial properties. α-Phenylethyl alcohol has a soft, positive as well as resilient increased scent. It is extensively utilized in the scent manufacturing industry for aroma adjustment, and is made use of alike soaps, cosmetics as well as perfumes. There is an excellent need both at home and also abroad.

It is utilized in large amounts when blending bitter neroli oil and also jasmine oil, as well as is utilized as the main part of climbed scent for the synthesis of various rose oils and also essential oils. It only needs to be added in a small amount in all flower fragrance blends, high-end perfumes and lotions. Very good effect, Styrax is a type of flavor that is popular amongst people and also it is steady to alkali. It is commonly utilized in soap essence and is an important flavor for mixing all climbed scent series essences. It is utilized in clove, orange blossom, It can be made use of in big amounts in many flower scents such as ylang-ylang, hyacinth, and also lily of the valley.

Styrax also has the result of repelling mosquitoes, as well as can be used to make insect repelling and also mosquito-repelling incense. It can also be utilized in percentages in food tastes, and is commonly made use of to prepare the aroma high quality of gewurztraminer and also yellow rice red wine. It is additionally commonly utilized as one of the fragrance chemical parts. It is used to regulate the flavor of flue-cured tobacco and boost the high quality of cigarette smoking as well as scent. Additionally, phenethyl alcohol is an important drug intermediate in the synthesis of many medications. For example, in the synthesis of “ibuprofen”, a sedative drug, Styrax is an important resources. This catalytic synthesis path of the medicine is considered to be very A significant development with economic worth as well as environmental management significance.

Dehydration of Styrax

Dehydration of Styrax to styrene was carried out in an Alloy 20 activator (4.3 ml. D. x 13 m) and also catalyzed by the addition of p-toluenesulfonic acid (pTSA). The reactor was operated at 26 Ombara (6 kPa), 204 ° C and also heated by 5 lbara (5100 kPa) heavy steam using an internal exchanger. Styrax was fed into the activator at a price of Mt/h as well as pTSA (130 ppm by weight of the 1-phenylethanol feed) was injected through a sparger situated at the bottom of the reactor. The conversion of Styrax was controlled at 94% by including PTSA. The vapors were dealt with in a scrubber to stay clear of PTSA carryover and the pTSA consisting of water stream was returned to the activator. The catalyst was purged from the bottom of the activator in addition to some unwanted heavy deposits.

Preparation of Styrax

Currently known synthetic methods for preparing Styrax mainly include: microbial fermentation, organic synthesis and other main methods.

Method 1: a preparation method of Styrax, said Styrax is prepared by heterogeneous hydrogenation reaction, comprising the following steps: raw material acetophenone, solvent water and catalyst are added in the reactor, and said catalyst is supported cobalt base catalyst or supported copper-based catalyst; seal the reactor, and replace it three times with nitrogen and hydrogen respectively; provide hydrogen source, control the pressure in the reactor to be 0.50~3MPa, and the stirring speed is 500~1000 rpm, at 70 Reaction at ~120°C for 2-10 hours, one-step reaction to obtain the α-phenethyl alcohol.

Method 2: a method for preparing α-phenylethyl alcohol with a magnesia/graphene hybrid material as a catalyst, the preparation method of the magnesia/graphene hybrid material catalyst comprises the following steps:

1) Preparation of graphene oxide suspension: take graphene oxide and disperse it in distilled water, and after ultrasonication for 1-3 hours, a brown-yellow graphene oxide suspension is obtained;

2) Preparation of magnesium salt solution: dissolving magnesium salt in distilled water to obtain a clear magnesium salt solution;

3) Preparation of magnesium hydroxide/graphene oxide: Dissolve ammonium bicarbonate in distilled water to make a clear ammonium salt solution, and add it to the graphene oxide suspension prepared in step 1), then add ammonia water and mix well to obtain Brown-yellow graphene oxide ammonium salt solution mixed solution; under stirring, the magnesium salt solution obtained in step 2) is dropped into the mixed solution drop by drop to obtain brown-yellow magnesium hydroxide/graphene oxide precipitate; after standing for 24 hours , placed in a water bath at 80-90°C and stirred for 4 h, filtered while hot, washed with distilled water until the filtrate was neutral, and the filter cake was exposed to the air for 24 h to obtain a gray magnesium hydroxide/graphene oxide powder cake;

4) Preparation of magnesium oxide/graphene hybrid material: place the magnesium hydroxide/graphene oxide powder cake obtained in step 3) in a drying oven at 100 °C for 24-28 h, and then roast in the air to obtain gray magnesium oxide/graphite ene hybrid materials.

Method 3: A preparation method of Styrax, the method is: under normal pressure, acetophenone is used as raw material, alcohol is used as hydrogen source, and supported alkaline earth metal oxide is used as catalyst, at a reaction temperature of 60-130°C After reacting for 1-10 hours, after the reaction is completed, the reaction solution is processed to obtain α-phenylethanol; the alcohol is C1-C7 aliphatic alcohol or C3-C7 alicyclic alcohol; the amount of the acetophenone and likewise alcohol is in between The percentage is 1:5 -30; the supported alkaline planet steel oxide is made up of a company in addition to an alkaline world metal oxide filled on the service provider, the alkaline world steel oxide is MgO, CaO, SrO or BaO, and the provider is triggered carbon, the loading amount of the alkaline earth steel oxide is 0.5-15wt% based upon the mass of the service provider.
