WebQuestion: Phenols generally have lower pk, values than aliphatic alcohols owing to phenoxide ion stabilization by resonance that delocalizes charge into the aromatic ring. … WebGenerally, aliphatic alcohols are of a low volatility and as a rule engineering controls are available preventing the need for respiratory protection. For non-routine operations involving a break in enclosed systems a higher level of protection is applied. Operations with a potential for significant exposure require a permit to work system and ...
WebBoth are aliphatic alcohols, meaning that they are derived from a hydrocarbon and do not contain a benzene group. There are three classifications of aliphatic alcohols.
