China - GBL is another name of the chemical substance which name is ¦Ã-Butyrolactone. This substance has features of colorless, oil temperament, easy soluble in water and slight odor. This substance can be used as a solvent in the aluminum electrolysis and could also be used as detergent, paint removers and others.
As the introduction of technician from famous buy gamma butyrolactone cleaner seller www.gammabutyrolactonecleaner.com , this chemical substance is one kind of colorless transparent oily liquid with the properties of certain moisture absorbing and a slight odor. It could be dissolved into water, alcohols, esters, ethers, ketones and straight-chain alkanes and cycloalkanes. The freezing point of it is -43.53 Celsius and the boiling point is 206 Celsius. The relative density of the GBL is 1.129 and refractive index is 1.4362. This chemical substance could be volatilized with the water steam and be decomposed in hot alkaline solution.
The method for Preparation of the GBL could be mainly divided into two types. The first one is the maleic anhydride hydrogenation which had been developed in 70 years. By the hydrogenation reactions, it could be able to produce any proportion tetrahydrofuran and ¦Ã- butyrolactone. There are many related manufacturers which use this method. The second one is the 1, 4- butanediol dehydrogenation methods. The reaction temperature of this method will be controlled at 230 to 240 Celsius degrees. The yield rate is more than 77 percent.
For the application of the PURE GBL, the technician said that this substance is a highly soluble, non-toxic and high -boiling solvents with very easy management and convenient. This kind of chemical substance could be used as extraction agent for butadiene, aromatics, senior grease production in petroleum industry. In the chemical fiber industry, the GBL could be used as the spinning solvent to dye the auxiliaries wool, nylon , and acrylonitrile fibers.
In the producing process of organic synthesis, the PURE GBL also has very wide range of application. It is the main raw materials for the synthetic production of ¦Á-pyrrolidone, N- methylpyrrolidone, vinylpyrrolidone, acetyl-¦Ã-butyrolactone, cyclopropylamine and other chemical materials. On the other hand, the GBL is also very crucial intermediates for the synthetic to pesticides, weed agents, drug piracetam, ciprofloxacin, vitamin B1, chlorophyll and others. Furthermore, this chemical material could also be used for the synthesis of butyric acid chlorophenoxy herbicides, plant growth regulators and many other very useful agricultural used chemical substances.
