Description

  The present invention relates to a novel process for producing a chain aliphatic diol. The chain aliphatic diol of the present invention is useful as an intermediate for a polyester resin monomer raw material, a polyurethane resin additive, and a medical and agrochemical raw material.

  In recent years, chain aliphatic diols have attracted attention as monomer raw materials for polyester resins and polyurethane resin additives. In any case, it is used as a monomer raw material or an additive having 6 or more carbon atoms and having a chain-structured aliphatic hydrocarbon in the skeleton and having a hydroxyl group at the terminal.

  For example, decanediol having 10 carbon atoms is produced through the production of sebacic acid by alkali melting of castor oil (see, for example, Non-Patent Document 1).

  However, there are problems such as an alkali melting process that is difficult to handle due to severe reaction conditions, and that it is difficult to convert to a diol because of an intermediate of a dicarboxylic acid structure.

After 1 hour, after cooling to room temperature, 8 ml of saturated sodium chloride solution was added to the reaction solution, and methanol was distilled off. Then, it extracted 3 times with 10 ml of diethyl ether, and dried with magnesium sulfate.

Was analyzed by gas chromatography, 1,12-hormones carboxymethyl 2,10 dodecadiene was completely converted, the selectivity of 1,12-dihydroxy-2,10-dodecadiene was 95%.

Example 18
A 50 ml two-necked eggplant flask was charged with 10 ml of ethanol and 0.02 g of 5 wt% Pd / C and 5 mg of sodium hydroxide as a hydrogenation catalyst, and the atmosphere was replaced with nitrogen. Thereafter, hydrogen was supplied to the flask at 15 ml / min, and reduction treatment was performed at 50 ° C. for 2 hours.

  The temperature in the flask was lowered to 27 ° C., and 0.15 g of 1,12-hydroxy-2,10-dodecadiene obtained in Example 17 was added. After 20 hours, the reaction solution was taken out and analyzed by gas chromatography. As a result, 1,12-dihydroxy-2,10-dodecadiene was completely converted and the selectivity of 1,12-dodecanediol was 82%.
