phenate

Dichlorocarbene will react in the ortho-position of the phenate (5) to give dichloromethyl substituted phenol (7).

The agency says it has insufficent evidence of human risk in the others: thiabendazole, ortho-phenylphenol, sodium ortho-phenyl phenate, imazalil, dicloran and sodium borate.

Polyphenyl ethers (PPEs) are obtained by repeated application of the Ullmann Ether Synthesis: reaction of an alkali-metal phenate with a halogenated benzene catalyzed by copper.

The PH Helmet (Phenate Hexamine) replaced it in October 1915, and added hexamethylene tetramine, which greatly improved protection against phosgene and added protection against hydrocyanic acid.
