40433-82-7 - Introduction
Pinusolidic acid, also known as rosin acid or rosin acid, is an organic acid with the chemical formula C20H30O2. The following is a description of the nature, use, formulation and safety information of Pinusolidic acid:
Nature:
1. Appearance: Pinusolidic acid is a light yellow crystal, soluble in ethanol and chloroform, slightly soluble in water.
2. Melting Point: about 150-155 ° C.
3. Toxicity: Pinusolidic acid has certain toxicity, and long-term exposure or large intake may have negative effects on human health.
Use:
1. Industrial application: Pinusolidic acid is widely used in the preparation of resin, needle essence and turpentine.
2. Medical application: Pinusolidic acid is used as an external disinfectant or antibacterial agent in some drugs.
3. Cosmetic application: Pinusolidic acid is also commonly used in cosmetics as a preservative.
Preparation Method:
1. Pinusolidic acid can be extracted from turpentine. First, the turpentine is distilled and extracted to obtain refined turpentine. Then, the components in the turpentine are converted into Pinusolidic acid through reactions such as acidification, hydrolysis or hydrogenation.
2. Another preparation method is through microbial fermentation, using some specific strains to produce Pinusolidic acid.
Safety Information:
