Green chemistry: chloroform or cyclohexane? 


Best insight from top research papers

Green chemistry aims to reduce environmental risks and promote sustainable development. It involves the use of environmentally friendly solvents, such as green solvents, which are less toxic and can be derived from renewable resources . Chloroform and cyclohexane are conventional solvents derived from the chemical industry and are toxic to human health and the environment . However, there are methods to synthesize chlorocyclohexane using green chemistry principles, which can achieve high selectivity and reduce production costs . The use of catalysts and halogenating agents, such as thichloroisocyanuric acid and copper complexes, can facilitate the conversion of cyclohexane to chlorocyclohexane with high selectivity . Therefore, in the context of green chemistry, cyclohexane is a preferred choice over chloroform for the synthesis of chlorocyclohexane .

What ist the problem with chloroform?4 answersChloroform has several problems associated with its use. Firstly, it can deteriorate samples dissolved in NMR solvent, leading to abnormal NMR spectra and affecting non-targeted analysis methods. Secondly, chloroform can cause adverse effects such as drowsiness, nausea, and liver damage. Additionally, chloroform is carcinogenic in rats, mice, and possibly in dogs, causing the development of malignant tumors in various organs. Furthermore, chloroform proved to be hazardous when administered by individuals lacking the necessary skill and understanding, with sudden cardiac events occurring more frequently than with ether and hepatic injury attributed to delayed chloroform poisoning. Overall, the problems with chloroform include its impact on NMR spectra, adverse effects on health, carcinogenic properties, and the potential for hazardous administration.
