KNOW HOW: Production of Macrocyclic Musk Perfumes by Chemical Synthesis   
Usage: Bioengineering Technologies And Products
Keyword: Ethylene brassylate (Musk-T)
Remarks:  FRIPP also strives in developing down-stream products of DCA by chemical synthesis, such as Musk-T, Hot-melt adhesives and other fine chemicals.
 Ethylene brassylate (Musk-T), a kind of macrocydic esters, is obtained by chemical synthesis from Brassylic acid (DCA13). It is a high quality musk compound and similar to natural musk in molecular structure. Musk-T can be used to manufacture shampoo, cosmetics and toiletry.
 FRIPP has synthesized this product with DCA13 by chemical method and developed a high activity catalyst. The synthesis reaction is:                   O=C (CH2) 11C=O
   HOOC(CH2)11COOH + HO(CH2)2OH→ | |
                     O (CH2) 2O          
 The purity of product is higher than 97%. This technology is characterized by high yield, good quality, simple process and no special environmental problems. The quality of Musk-T is listed in table2.
