What is Ethylene Brassylate?

Ethylene Brassylate is a long-lasting musky fragrance with a greasy smell. It is a liquid with a melting point of 5℃ and a boiling point of 332℃. It is an important musk fragrance known as tridecanedioic acid cycloethylene vinegar or Kunlun Musk in China. It is widely used in perfume, cosmetic, and soap formulations due to its excellent fixative and diffusibility properties. Musk T, the largest-producing macrocyclic musk, is mainly manufactured by Japan’s Takasago Flavor Company with an annual output of about 200t. The name Muscat is derived from the unique aroma emitted by the glandular secretions of male musk deer in Southeast Asia. Musk has been favored as the “King of Spices” in the spice industry for its elegant, mild, deep, and vivid aroma, as well as its moisturizing and fragrance-enhancing abilities.

Ethylene Brassylate Uses

  1. Ethylene Brassylate is a versatile ingredient used in food flavors, including vanilla, cinnamon, cherries, and trace amounts in tropical fruits.
  2. It is also utilized as a fragrance preserver for spices and is commonly found in soaps, toilet water, and detergents.
  3. Additionally, Ethylene Brassylate serves as a fixative and synergist for botanical floral fragrances.

Ethylene Brassylate Synthesis Method

Ethylene Brassylate can be obtained by polymerizing tridecanedioic acid (brazilic acid) and ethylene glycol, and afterwards depolymerizing and cyclizing it (Hebei Chemical Industry, 1992, № 4, 28).
There are 3 manufacturing methods for tridecanedioic acid, which is a raw material for the production of Ethylene Brassylate.
Among the methods is the undecenoic acid synthesis route. Because of the long synthesis course, low total yield (~ 40%), and high price, it is in fact no more used.
The second approach is n-tridecane fermentation and oxidation technique. This method has the advantages of simple accessibility of raw materials, simple process and affordable. The drawback is that the purity of the item is not high (<95%), and some new by-product impurities are produced during the fermentation procedure that are very challenging to eliminate, which will create the musk T product to be low in pureness and have a foreign scent.
The 3rd method is the erucic acid ozonation course. The benefits of this technique are that the raw products are quickly readily available, the procedure steps are couple of, the overall return is greater than 48%, the cost is low, the product pureness is high (96% to 98%), and the purity can be enhanced by recrystallizing toluene. For that reason, this approach can be taken into consideration to have one of the most advancement prospects.
The depolymerization reaction of polyester is the vital technology in the process of synthesizing Ethylene Brassylate. The initial step is to select an efficient depolymerization driver to acquire high return products. In order to make certain good warm transfer result of the reactor in industrial manufacturing, it is important to pick efficient heating techniques and associated stirring device problems.

Preparation Method of Ethylene Brassylate

Initially, put a, ω-tridecanedioic acid, 1,2-ethylene glycol and polymerization prevention right into the polymerization response vessel symmetrical, and start home heating at a particular home heating rate. After a, ω-tridecanedioic acid After partially dissolved, start mixing and begin the response when it reaches 180C. The water created by the response is distilled from the gas stage outlet pipe on the top of the cauldron, and afterwards compressed right into the polymerization receiving container. When the gas stage temperature drops substantially and no gas is created, the normal pressure polymerization is finished. Atmospheric pressure polymerization needs to be accomplished under nitrogen security to avoid oxygen in the air from presenting side reactions such as oxidation and fracturing. Maintain the reduced pressure for a specific amount of time, evaporate excess 1,2-ethylene glycol, and remove the gaseous items. When the acid value of the polyester is less than 1.6 KOHmg/g, the polymerization reaction ends.

Vacuum degree control in the vacuum polymerization process is an extremely important issue for the ethylene glycol tridecanedioic acid device. In this personification, vacuum purification is carried out in the vacuum system to recoup excess 1. For 2-ethylene glycol, the temperature level is managed at about 180C and the pressure has to do with 20Pa. After the healing of 1,2-ethylene glycol is completed, close the vacuum cleaner valve.

After the polymerization response is completed, include the stimulant, stir evenly, and pour the polyester right into a depolymerization reactor that has actually been increased to 230 ° C. Usage a vacuum pump to evacuate and do the depolymerization reaction under lowered stress. As the response earnings, the thickness of the material requires to remain to enhance, the heat transfer impact worsens, and the temperature requires to remain to climb. The unrefined ethylene glycol tridecanedioic acid produced by the reaction comes out of the kettle, and goes into the crude item receiving storage tank after condensation. When the gas stage temperature level drops and no item distills out, the depolymerization reaction ends.

The technique is to initial flash distillate the head portion, then rectify and accumulate the fractions under vacuum and 285 ~ 315C conditions, and finally accumulate the ended up product via flushing and dissipation. The crude product has a small amount of 1,2-ethylene glycol and lighter front portions and lighter Heavy dimers, trimers, and so on are obtained via intermittent purification to obtain the ended up item Musk-T: the residual fluid consists of dimers, trimers, and so on with larger molecular weights, which can be returned to the depolymerization pot for re-depolymerization. Hereafter process, the web content (gas chromatography) is raised from ≥ 97% to ≥ 98%, and the fragrance is reasonably pure.

In this embodiment, both basic materials of a, ω-tridecanedioic acid and 1,2-ethylene glycol are 1:1.

In this embodiment, the depolymerization catalyzer is a very energetic composite depolymerization catalyst, which is made up of aluminum carbonate and p-toluenesulfonic acid, silicotungstomolybdic acid, anhydrous copper sulfate and water in the ratio of 1.5:1:1:0.5: After dissolving in a ratio of 6, include granular silica of the same mass as the dissolved option. After complete adsorption, area it in a stove and completely dry the water at 105 ° C.
