| titleOfInvention | Dispersant for inorganic powder in oil |
| abstract | PURPOSE: To shorten the time required to disperse inorg. powder in oil and to increase the dispersion stability by preparing a dispersant with a salt of polyester sulfonic acid obtd. by sulfonating reactive double bonds in polyester having maleic acid units. n CONSTITUTION: A polyhydroxy compd. is added to maleic anhydride in the presence of an ordinary esterification catalyst in (0.5W1.5)/1 equiv. ratio of hydroxyl groups to carboxyl groups in the polycarboxy compd. and esterification is carried out at 80W300°C while blowing an inert gas. Sulfonation is then carried out with a sulfonating agent to obtain a desired salt of polyester sulfonic acid and a dispersant for inorg. powder in oil is prepd. with the salt as an effective component. The dispersant is used by 0.05W10 pts.wt. per 100 pts.wt. inorg. powder. n COPYRIGHT: (C)1989,JPO&Japio |
