Theoretical organic chemistry Physical properties of benzene homologues
Once in the laboratory I conducted an experiment and noticed that toluene has a characteristic smell, but not sharp, like, for example, benzene, ethylbenzene, cumene, and other benzene homologues, which are very difficult to work with even under traction. Therefore, I began to use toluene as a non-polar solvent. And it's really much more comfortable to do experiments with him. How can this be explained? What do you think?
Sense of smell is a very complicated one, 'cause it's based on numerous receptors. Toluene probably hits just the right spot in some kind of key-lock structure.
Sometimes even the smells of the same substance in different concentrations are felt differently.
Perhaps this is due to the shelf life of chemical reagents.
But actually I wouldn't recommend using toluene much. My colleagues souly believe that it's very canserogenous
The toxicity of toluene is much lower than benzene Experiments on rats did not reveal the risks of an increase in the number of tumors with long-term exposure to toluene. However, there are currently no data on carcinogenic effects on humans.
