Resin acid refers to mixtures of various carboxylic acids, especially abietic acid, found in tree resins. Almost all resin acids have the same basic skeleton. Resin acids are sticky and yellowish gums that are insoluble in water.
Resins are generally mixtures of organic compounds. Plants secrete protective resins in response to injury. The resin protects the plant from insects and harmful pathogens. Most plant resins consist of terpenes. Some resins contain high resin acids.
Resin acids are formed by combining two- and three-carbon molecules with isoprene building units to form monoterpenes (volatile), sesquiterpenes (volatile), and diterpenes (non-volatile) structures.
Natural resin obtained from tree trunks is abietic acid. It must be neutralized before use. Usually this is done by reacting it with lime. The neutralized resin is highly glossy and retains its shine for a long time, and it also has a high tendency to stick. Dry resin is very weak in resistance to water and chemicals. It is generally used in making polishes.
Advanced laboratories employ simple, fast and accurate test methods to measure resin acids in liquid or solid samples. Monitoring of resin acid content throughout the production process is required in enterprises due to its harmful effects on operating waste. Gas chromatography is the most widely used method for analyzing resin acids.
In the tests and analyzes carried out in our institution, which has a wide range of technological equipment, trained and experienced staff and applies the most modern methods, national and international standards and legal regulations in force are complied with. Among the numerous tests carried out in this context, there are also services for the determination of resin acid.
