What is Musk T?

Musk T has a strong musky scent, long-lasting, however with a greasy smell. The look is liquid, the melting point is 5 ° C, the boiling point is 332 ° C, 138 ~ 142 ° C/133Pa.
According to the information given by RIFM, the intense poisoning information of musk T: oral LD50 > 5g/kg (rat), skin test LD50 > 5g/kg (rabbit).
Musk T is a vital range of musk fragrance. Its chemical name is tridecanedioic acid cycloethylene ester. It is additionally called Kunlun musk in China. It belongs to high value-added great chemical items. It is a superb fixative with good diffusivity., lasting scent. It is extensively utilized in perfume essence, cosmetic essence and soap essence formula. IFRA has no constraints.
Musk T is the most efficient variety among macrocyclic musks. The existing yearly output has to do with 200 heaps, accounting for regarding fifty percent of the complete manufacturing of macrocyclic musks. The primary maker is Japan Takasago Fragrance Business.
The name Muscat may be stemmed from the one-of-a-kind scent emitted by the glandular secretions of male musk deer in Southeast Asia. In the fifth century advertisement, this secretion was used to make uncommon fragrances. Musk is referred to as the “King of Spices” by the fragrance market and also has actually constantly been preferred by individuals. The fragrance of musk is classy, light, deep as well as brilliant, and it has a great moisturizing impact and also scent enhancing capacity in mixing spices.

Musk T Uses

  1. Musk T is used for flavoring. Used in vanilla, cinnamon, cherries, exotic fruits (trace amounts), etc.
  2. Musk T is a reliable fragrance-preserving agent for fragrances, utilized in soaps, toilet water, cleaning agents, and so on.
  3. Musk T is made use of as a fixative as well as synergist for plant-floral fragrances.

The Synthesis Method of Musk T

Musk T can be formed by polymerization of tridecanedioic acid (brazil acid) and ethylene glycol, adhered to by depolymerization and also cyclization (Hebei Chemical Industry, 1992, № 4, 28).
There are three making approaches for tridecanedioic acid as a raw material for the production of musk T.
One of the techniques is the undecylenic acid synthesis route. Because of the lengthy artificial path, reduced overall return (~ 40%), and high expense, it has not been made use of in practice.
The second technique is n-tridecane fermentation oxidation technique. This approach has the advantages of easy-to-obtain raw materials, simple procedure and also inexpensive. The downside is that the purity of the item is not high (<95%), and some brand-new byproduct pollutants that are very challenging to remove will certainly be generated throughout the fermentation procedure, which will certainly trigger the musk T item to have a low purity and also a heterogeneous smell.
The 3rd approach is the ozonation path of erucic acid. The benefit of this method is that the raw products are easy to get, the process steps are few, the complete return is greater than 48%, the price is low, the item pureness is high (96%-98%), and the purity can be enhanced by toluene recrystallization. For that reason, it can be taken into consideration that the legislation is the most appealing.
The depolymerization reaction of polyester is the key technology in the process of manufacturing musk T. To start with, it is essential to choose a highly efficient depolymerization driver to obtain high yield items. In order to ensure the excellent warm transfer result of the reactor in industrial production, it is really essential to choose a reliable home heating approach and the relevant stirring device.

The Preparation Method of Musk T

First put a, ω-tridecanedioic acid, 1,2-ethylene glycol and polymerization inhibitor into the polymerization response container symmetrical, start to heat up at a specific home heating rate, as well as wait on a, ω-tridecanedioic acid Beginning stirring after partial dissolution, and begin the reaction when it reaches 180C. The water generated by the response is distilled from the gas stage electrical outlet pipeline at the top of the storage tank, as well as enters the polymerization receiving tank after condensation. When the temperature of the gas phase drops considerably and no gas is produced, the normal stress polymerization is completed. Air pressure polymerization needs to be performed under the protection of nitrogen to stay clear of side reactions such as oxidation as well as splitting presented by oxygen airborne. Maintain the minimized stress for a certain amount of time to boil down off the excess 1,2-ethylene glycol as well as discharge the gas items. When the polyester acid worth is lower than 1.6 KOHmg/g, the polymerization response ends.

Vacuum control in the vacuum polymerization procedure is an incredibly important concern for the ethylene tridecanedibasic acid plant. In this personification, vacuum distillation is performed in the vacuum system to recover excess 1, 2-Ethylene glycol, currently, the temperature level is managed at about 180C, as well as the stress is about 20Pa. After the recuperation of 1,2-ethylene glycol is completed, shut the vacuum cleaner shutoff.

After the polymerization response mores than, include the catalyst, stir evenly, put the polyester into the depolymerization reactor that has actually been elevated to 230 ° C, make use of an air pump to leave, and also carry out the depolymerization reaction under minimized pressure. As the response proceeds, the thickness of the product requires to increase constantly, the heat transfer result comes to be inadequate, as well as the temperature needs to be continuously raised. The unrefined ethylene tridecanedibasic acid generated by the response is separated from the kettle, and also enters the unrefined item receiving tank after condensation. When the gas stage temperature level declines as well as no item is distilled out, the depolymerization response finishes.

Flash distillation is made use of very first to boil down the head portion, and then remedy and also gather fractions under vacuum at 285 ~ 315 ° C, and also lastly collect the finished product by flushing. The crude item consists of a percentage of 1,2-ethylene glycol as well as lighter front fractions as well as lighter fractions. Heavy dimers, trimers, etc, are obtained through set purification to acquire the completed musk-T: the raffinate contains dimers, trimers, etc with bigger molecular weights, and can be gone back to the depolymerization pot for re-depolymerization. Hereafter procedure, the material (gas chromatography) is raised from ≥ 97% to ≥ 98%, and also the scent is fairly pure.

In this example, both resources of a, ω-tridecanedioic acid and 1,2-ethylene glycol are 1:1.

In this embodiment, the depolymerization catalyst is a very energetic composite depolymerization driver, which is composed of aluminum carbonate, p-toluenesulfonic acid, silicotungstic molybdenum acid, anhydrous copper sulfate as well as water according to the ratio of 1.5:1:1:0.5: After the proportion of 6 is liquified, add granular silica of the same quality as the dissolved option, after complete adsorption, place it in an oven, and also dry the water at 105 ° C.
