The research group headed by Prof. Kong Qingchi of China University of Petroleum (East China) has successfully developed a brominated triazine flame retardant production technology. Compared with the technology commonly used in China, this technology has high conversion rate of tribromophenol, low production cost and good product chroma. In particular, the use of a unique non-aqueous solvent system in China completely solved the problem of hydrolysis of cyanuric chloride.
The technology is divided into tribromophenol production and bromine triazine production process. No waste gas and waste slag are produced in the two processes. The new process has mild reaction conditions, no side reactions, and easy control. The obtained product has stable quality and high melting point, which can improve the product's flame-retardant efficiency and make the product have good thermal stability and UV stability.
It is understood that brominated triazine flame retardant is a new bromine/nitrogen synergistic flame retardant, which is superior to ultraviolet radiation and light resistance, and is an upgraded substitute product of tetrabromo and decabromo. Its white appearance, large molecular weight, complex structure, good thermal stability and electrical properties, and excellent lightfastness. Because the product does not contain free bromine, it can avoid adverse effects on the processing equipment and the environment. It can make the processing equipment safer and the product performance is more excellent. It is especially suitable for plastic products that need to be processed at higher temperatures, such as ABS, etc. Widely used in electronic components, audio-visual equipment, instrumentation, insulation equipment and other production areas.
Ethyl Acetate (systematically ethyl ethanoate, commonly abbreviated EtOAc, ETAC or EA) is the organic compound with the formula CH3−COO−CH2−CH3, simplified to C4H8O2. This colorless liquid has a characteristic sweet smell (similar to pear drops) and is used in glues, nail polish removers, and in the decaffeination process of tea and coffee. Ethyl Acetate Plant is the ester of ethanol and acetic acid; it is manufactured on a large scale for use as a solvent.
Ethyl Acetate Prices is used primarily as a Solvent Raw Material and diluent, being favored because of its low cost, low toxicity, and agreeable odor.[citation needed] Boric Acid Flakes For example, Ethyl Acetate Solvent is commonly used to clean circuit boards and in some nail varnish removers (acetone is also used). Coffee Ethyl Acetate Of South Korea beans and tea leaves are decaffeinated with this solvent (when supercritical CO2 extraction is Melamine Powder not possible).It is also used in paints as an activator or hardener. Ethyl Acetate Industrial Grade is present in confectionery, perfumes, and fruits. In perfumes it evaporates quickly, leaving the scent of the perfume on the skin.
