WebThis method is less hazardous and produces a higher yield of salicylic acid, but it requires the use of specialized equipment such as a high-pressure reactor. A third method for synthesizing salicylic acid is the hydrolysis of acetylsalicylic acid, also known as aspirin.

In fact, far more salicylic acid was evolved at p H 7. This comes as a surprise to me because I expected an acid-catalyzed ester hydrolysis to actually quicken the rate of reaction and thereby evolve MORE salicylic acid. Web1 jun. 1988 · The hydrolysis rate constant of this ester increased as a function of the egg lecithin concentration in unilamellar liposomes suggesting a surface reaction was responsible for its catalytic degradation (Yotsuyanagi and Ikeda, 1980). driver licence application renewal
