6-Acetyl-1,1,2,4,4,7-HexaMethyltetralin（CAS:1506-02-1 ）technologyinnovation and industrialization demonstration

       6-Acetyl-1,1,2,4,4,7-hexamethyltetralin, chemical name is 1,2,3,4-Tetrahydro-1,1,3,4,4,6-hexamethyl-7-naphthyl methyl ketone. White crystal, melting point 55-56 ℃ ，is more high grade artificial musk ，is better than that of Galaxolide. Mainly used to reconcile spices, widely used in soaps, cosmetics, perfume and bath oil. As a substitute of natural musk, convenient, cheap price, the product has higher boiling point, lasting aroma characteristics, the highest dosage can be more than 10%, is a good fixative. It is safe to use by the internationally recognized, an ideal flavor not harmful to human skin, has been in the international market best-selling  . At the same time ，6-Acetyl-1,1,2,4,4,7-hexamethyltetralin When light is not chromophore ，do not change color， so it than macrocyclic musk or musk has better production conditions and high economic value. Through the market survey, in 2013 ，the global annual demand in 3000t/.

     As the market continues to expand the scale of domestic manufacturers, the fierce competition of international counter parts in the scale of production and quality. At present the domestic manufacturers generally small scale, quality deviation, two step by the traditional production process, the production cycle is long, efficiency is low, leading to high production costs, so the general retail price of domestic manufacturers to achieve 200000RMB/tons. Irritation to the other technology used in inflammable and explosive materials, acetyl chloride to further increase the production of environmental governance costs and security risks. In order to further weaken the competitiveness of products in the international market. The subfamily joint domestic famous universities, after nearly 2 years of painstaking research, yacoo company developed from a unique proprietary technology, process route is shortened by two step into one step, which greatly improves the production efficiency, one-step yield up to 95%, the musk altonide production cost is reduced by more than 20%, at the same time by acetyl raw materials more green subfamily environmental protection, no longer using acetyl chloride raw material of traditional, make the whole production process is more green, safe and reliable. The subfamily has been initially built an annual output of 200 tons of production line model, plans to build in 2015 industrial production line of 1500 tons per year, to further enhance the product competitiveness and brand influence in the domestic and international market.
