説明

1) Higher fatty alcohol showed a property to peptize the gel of metal soap and mineral oil, such as lubricating grease, especially those of calcium, barium or magnesium soap.<BR>2) The method of quantitative estimation of the minimum (on necessary) dosage to give a stable gel has been studied on the calcium-stearate-mineral oil system as an example.<BR>3) The minimum dosage of the higher alcohol with various numbers of carbon atom necessary for stable gel formation was measured and the result obtained showed that the minimum dosage in weight percent is proportional to the mean molecular weight of alcohol and is almost constant in reduced mole concentration.<BR>The variation in metal soap concentration in the gel had only a small effect on the minimum dosage, but slight tended to decrease as the soap content increased.<BR>4) A comparison of the soap-gel phase diagrams of the colcium-stearate-mineral oil system containing higher alcohol with that containing water, proved an evident difference in function between the alcohol and water.<BR>5) From the experiment, carried out as an example of application to lubricating greare, it was verified that higher alcohol can be used as a peptizer or stabilizing agent of lubricating grease.
