NEW MATERIAL:A compound expressed by formula I (R 1 and R 2 are 5C alkyl, provided that R 1 may be the same as R 2 ; R 3 is 8W12C alkyl) and formula II(m is an integer 2W4; n is the polymerization degree and about 10 on the average). n EXAMPLE: 3,5,5-Trimethylhexyl isomyristate. n USE: A lubricant for magnetic tapes, having improved lubricating ability and pour point characteristics rendering the magnetic tapes usable within a wide temperature range. The application to lubricating oils, etc. can be considered from the hydrolytic resistance. n PREPARATION: Heptanol is subjected to the Guerbet reaction in the presence of a sodium alcoholate, etc. and a metal catalyst under refluxing and heating, and the formed water is continuously removed to the outside of the system and produce the aimed myristyl alcohol expressed by formulas III and IV, which is then oxidized by an alkali fusion and oxidation reaction to give isomyristic acid. The resultant isomyristic acid is then refluxed with an alcohol in the presence of an azeotropic solvent and esterification catalyst under refluxing and heating to afford the aimed compound expressed by formula I. n COPYRIGHT: (C)1986,JPO&Japio |
