9-DECEN-1-OL synthesis

11synthesis methods
From 1,10-decamethylene glycol (Arctander, 1969).
-

Yield:13019-22-2 88%

Reaction Conditions:

with 1-hexadecylcarboxylic acid at 340; for 5 h;Molecular sieve;Temperature;Reagent/catalyst;

Steps:

1-1 Synthesis of 9-decenol (Cyclic reaction)
18 g of the vacuum distillation bottoms liquid obtained in the step 2) of Example 1 was mixed with fresh raw material - 1,10-decanediol (which may be mixed in any ratio), and the resulting mixture was used in place of that used in the step 1) 1, 10-decanediol was continuously fed and then the reaction was continued according to the process conditions of step 1) of Example 1; namely, the discharge rate was adjusted to 30 g / h, and the feed rate was adjusted to be consistent with the discharge rate .The reaction was continued for 6 hours, feeding 190 g and discharging about 180 g.And then subjected to atmospheric distillation and vacuum distillation as in Example 1, step 2) to obtain 9-decenol, yield 88%, and purity 99.3%.Based on the above data, we know that the above-mentioned cyclic reaction does not affect the final yield and product purity.
