Production
of Macrocyclic Musk Perfumes by Chemical Synthesis
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.
