What is Rose Ether?

Rose ether, also known as Rose Oxide, is an important seasoning that exists in Bulgarian increased oil, geranium oil and also a range of blossoms, fruits, white wines and also insect secretions. In nature, it exists as (-)-(4R)-cis body and also (-)-(4R)-trans body, mostly cis body, with sharp and clear yard scent and also climbed fragrance. The cis body has a delicate fragrance, its levorotatory scent is sweet, as well as the trans body has a solid environment-friendly scent and is accompanied by some flavor. Generally made use of for rose type as well as geranium kind as well as other tastes, the dose is 0.01%-0.2%.

Preparation of Rose Ether

At home and abroad, the synthetic process route of rose ether has been studied since the last century. It mainly uses citronellol as raw material and is synthesized by oxidation. In the oxidation process, peroxides were mostly used for oxidation in the past, but this method is very dangerous and difficult to control the reaction. In the process, explosion may occur, and there are many by-products, low yield and high cost, which are gradually being eliminated. At present, the photosensitive oxidation process is emerging, and there are also researches on photosensitive oxidation in China, but the technology is immature and the product yield is low, so it is difficult to enlarge and implement industrialization. Therefore, developing a new process for oxidative synthesis of rose ether to achieve high yield, low cost and safe production of rose ether is of great significance for promoting scientific and technological progress in the fragrance industry and meeting market demands.

CN201210535789.1 provides a photosensitive oxidation synthesis process of rose ether, which can overcome the shortcomings of the prior art.

The present invention includes the following steps:

(1) Citronellol (C10H20O) is photosensitively oxidized to generate peroxycitronellol (C10H19OOOH). Add a certain amount of citronellol to the reaction kettle, then add 80%-99% methanol with 1.5-4 times the volume of citronellol, and methylene blue powder with a mass of 0.2%-1.5% citronellol, and stir evenly. Pour oxygen into the above-prepared solution, so that the flow rate of oxygen is controlled at 1-4kg/h, and the reaction kettle is kept at normal pressure; at the same time, light is given with an iodine-tungsten lamp, and the light intensity on the liquid surface is 20000-80000LX, and the stirring is continued. , Pour in condensed water and control the reaction temperature at 30-50°C, so that the reaction lasts for 10-50h, the entire reaction process is assisted by ultrasonic waves, and the cavitation effect of ultrasonic waves is used to improve the reaction speed and product yield. In this reaction, oxygen oxidizes citronellol to peroxycitronellol in the presence of methylene blue as a catalyst and light.

(2) Peroxycitronellol is reduced to citronellol (C10H19OOH). The temperature of the liquid in the reactor is raised to 40°C-50°C, 50%-80% methanol is recovered under reduced pressure, then distilled water with 1.8-4.0 times the volume of citronellol and sodium sulfite with 1.0-1.5 times the mass of citronellol are added, The reaction is carried out while stirring, and the reaction lasts for 6-30 hours. In the reaction, sodium sulfite reduces peroxycitronellol to citronellol, and sodium sulfite is oxidized to generate sodium sulfate. After the reaction is completed, the liquid is left to stand for stratification, the lower water layer is discharged into the sewage tank, and the upper organic layer is used for later use. The upper organic layer contains a large amount of citronella diol.

(3) Citronella diol is cyclized to form rose ether (C10H18O) under acidic conditions. To the upper organic layer, add dilute sulfuric acid with a volume of 8%-25% of citronellol and a mass fraction of 3%-15%, stir and react for 5-25 hours, and then add 4%-10% by volume of citronellol with a mass fraction of 10%-20% sodium carbonate aqueous solution, after neutralizing excess sulfuric acid, the reaction is naturally terminated. Stop stirring, let stand for stratification, the lower water layer is discharged to the sewage pool, and the upper organic layer is dehydrated and used for later use. The upper organic layer contains a large amount of rose ether.

(4) Separation of rose ether. The upper organic layer is rectified, and the fractions are collected to obtain the rose ether product. Using the rose ether product obtained by the invention, the total mass fraction of rose ether cis-trans isomers is 90%-99.5%.

The invention is characterized in that citronellol is oxidized to citronellol with oxygen under the conditions of ultrasonic assistance, catalyst and strong light, and then the rose ether is obtained by reduction and cyclization. Compared with the direct oxidation of chemical reagents and the existing photosensitive oxidation technology, it has obvious advantages in technology. First, the specificity of the reaction of this technology is good, and the by-products are few, which is very important for the synthesis of monomer fragrances, and the conversion rate of the product is very important. high, the subsequent separation and purification is relatively easy; secondly, this technology has a short process route, mild reaction conditions and high safety; finally, the rose ether product produced by this technology has high purity, pure aroma and good quality.
