“…[46][47][48] Rosin derivatives can be obtained by modifying the double bonds and carboxyl double bonds. [49][50][51] The double bonds can be used for polymerization ( polymerized rosin), hydrogenation (hydrogenated rosin) and disproportionation (disproportionated rosin), while the carboxyl groups can be esterified (ethylene esterification), or undergo acid-base neutralization (alkaline earth metal resin salt) and hydrogenolysis (rosin alcohol). [52][53][54] For example, rosin can be used in the food industry as a food additive because of its toughness and non-toxicity.…”
Rosin is the characteristic natural renewable resources and one of the important chemical raw materials in China. In view of the unique hydrogenated phenanthrene ring skeleton structure of rosin, the...

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
