Phenol in the Berthelot reagent can be replaced by a variety of phenolic reagents, the most common being sodium salicylate, which is significantly less toxic. [1] This has been used for blood urea nitrogen (BUN) determinations and commonly is used to determine water and soil total and ammonia-N. Replacement of phenol by 2-phenylphenol reduces interferences by a variety of soil and water ...
It is mainly used for nylon and polyesters, [2] as well as epoxides. [3] The compound is prepared from 2-phenylphenol, which condenses with one equivalent of phosphorus trichloride. Heating that species in the presence of aluminium trichloride results in cyclization. The procedure is completed by hydrolysis. [4] [5]

2 is added with H 2 SO 4 to form phenol (Hock process). In addition to the reactions above, many other more specialized reactions produce phenols: rearrangement of esters in the Fries rearrangement [7] [8] rearrangement of N-phenylhydroxylamines in the Bamberger rearrangement [9] [10] dealkylation of phenolic ethers; reduction of quinones
Chemical safety includes all safety policies, procedures and practices designed to minimize the risk of exposure to potentially hazardous chemicals. This includes the risks of exposure to persons handling the chemicals, to the surrounding environment, and to the communities and ecosystems within that environment. [ 1 ]
