An Improved Method for the Determination of Acetyl Values of Lipids Applicable to Hydroxylated Fatty Acids

Food Coatings, Permeability of Acetostearin Products to Water Vapor

“…The finished products were analyzed for melting range, monoglvceride content (5), and hydroxyl value. The latter was determined according to the acetylation method of West et al (13), modified by using 1 part of acetic anhydride to 3 parts of pyridine.…”

Catalytic Hydrogenation of Methyl Laurate to Lauryl Alcohol

“…Hydroxyl number, the milligrams of potassium hydroxide equivalent to the hydroxyl content per 1 gram of sample, was determined using the pyridine-acetic anhydride method with minor modifications (74, 27,22,30). This consisted of acetylating 1 gram of the sample containing the hydroxyl compound, with a definite amount of a 25% mixture of acetic anhydride in pyridine by heating to 100°C.…”

VIII. Autoxidation of Oleic Acid, Methyl Oleate, and Oleyl Alcohol

“…Acetyl numbers were determined by the method of West, Hoagland, and Curtis (21). It ivas found necessary to neutralize the slight amount of acid in the commercial butyl alcohol before it was used to dilute the samples.…”
