propan-2-yl 16-methylheptadecanoate

Conditions: temp:275.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 4770 g of isostearic acid isopropyl ester (Emery 2310 isostearic acid isopropyl ester, sold by Emery Industry Inc., U.S.A.) and 239 g of a copper-chromium catalyst (made by Nikki) are charged in an autoclave having a capacity of 20 liters. Hydrogen gas is then added under a pressure of 150 kg/cm2 and the reaction mixture is heated to a temperature of 275° C. Hydrogenation was carried out under a pressure of 150 kg/cm2 at 275° C. for about 7 hours, and then the reaction product was cooled and the catalyst residue was removed by filtration, whereupon 3500 g of a crude product were obtained. The crude product was distilled under reduced pressure thereby obtaining 3300 g of a colourless transparent isostearyl alcohol as a distillate at 80° to 167° C./0.6 mmHg. The isostearyl alcohol (methyl-branched stearyl alcohol) thus prepared had an acid value of 0.05, a saponification value of 5.5, and a hydroxyl value of 181.4. Absorption was observed at 3340 and 1055 cm-1 by IR (liquid film) and at δ3.50 (broad triplet, --CHH2 --OH) by NMR(CCl4). It has been found from gas-chromatography that the alcohol consists of a mixture which comprises about 75% of the main component having a total carbon number of 18 (the total of m and n being 15 in the formula II) and the rest being composed of components having a total carbon number of 14 or 16, and that, in any case, branched methyl groups are located in the vicinity of the center of the main alkyl chain. the reaction product was cooled the catalyst residue was removed by filtration, whereupon 3500 g of a crude product were obtained The crude product was distilled under reduced pressure

Conditions: temp:275.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Into a 20 liters autoclave were charged 4770 g of isopropyl isostearate [Emery 2310, commercially available from Emery Co., Ltd. U.S.A.] and 239 g of copper-chromium catalyst (product of Nikki Co., Ltd.). Hydrogen gas was charged into the reactor under a pressure of 150 kg/cm2 and the reaction mixture was heated up to 275° C. After hydrogenation under 150 kg/cm2 /275° C. for about 7 hours, the reaction product was cooled, followed by removing the catalyst residue by filtration to obtain 3500 g of crude product. The crude product was distilled under reduced pressure thereby obtaining 3300 g of colorless transparent isostearyl alcohol as a fraction of 80° to 167° C./0.6 mmHg. The thus obtained isostearyl alcohol (monomethyl-branched isostearyl alcohol) had an acid value of 0.05, a saponification value of 5.5, and a hydroxyl value of 181.4. IR analysis (liquid film) revealed absorptions at 3340 and 1055 cm-1 and NMR analysis (CCl4 solvent) revealed an absorption at (δ)=3.50 (broad triplet, --CH2 --OH). According to the gas chromatograph, the alcohol was chiefly composed of about 75% of an alcohol whose number of carbon atoms in the alkyl group was 18, with the remainder being made of alcohols having alkyl groups with 14 and 16 carbon atoms. The branched methyl group was located substantially at the center of the main alkyl chain in all the alcohol components. the reaction product was cooled by removing the catalyst residue by filtration to obtain 3500 g of crude product The crude product was distilled under reduced pressure

Procedure: Into a 20 liters autoclave were charged 4770 g of isopropyl isostearate [Emery 2310, isopropyl isostearate, available from the Emery Co., Ltd. of U.S.A.) and 239 g of a copper-chromium catalyst (Nikki Co., Ltd.). Thereafter, hydrogen gas was charged into the autoclave at a pressure of 150 kg/cm2, followed by heating the reaction mixture to 275° C. After the hydrogenation under conditions of 150 m kg/cm2 and 275° C. for about 7 hours, the resulting reaction product was cooled, from which the solid catalyst was removed thereby obtaining 3500 g of a crude product. The crude product was distilled under reduced pressure to obtain 3300 g of colorless, transparent isostearyl alcohol as a distillate of 80° to 167° C./0.6 mmHg. The thus obtained isostearyl alcohol (monomethyl-branched isostearyl alcohol) had an acid value of 0.05, a saponification value of 5.5, and a hydroxyl group value of 181.4. The alcohol had absorption peaks at 3340 and 1055 cm-1 in the IR analysis and at delta 3.50 (broad triplet, --CH2 --OH) in the NMR analysis (CCl4 solvent). It was found from the gas chromatography that the alcohol was a mixture of alcohols which had about 75% of an alkyl group containing 18 carbon atoms in total with the remainder having 14 to 16 carbon atoms in total and whose branched methyl groups were positioned almost at the central portion of the alkyl main chain. the resulting reaction product was cooled, from which the solid catalyst was removed thereby obtaining 3500 g of a crude product The crude product was distilled under reduced pressure
