(1) But the fungicide, voronate, phenol and possibly ethyl acetate were among the chemicals of greatest concern to the marine environment.(2) He cited examples of two key raw materials namely phenol and aniline, which are required to manufacture leather chemicals, pigments, dyestuff and rubber chemicals.(3) Alternatively, low percentages of chemicals such as phenol , menthol, and camphor can be added to moisturizing lotions for added anti-itch benefit.(4) Industrially, benzene is used in the manufacture of nylon, phenol , styrene (and by polymerization polystyrene), and cyclohexane.(5) Believing that not all samples of aniline oil worked consistently, Ziehl substituted phenol (carbolic acid) in its place.(6) Sebacic acid can be synthesized from phenols and cresols, but castor oil oxidation is considered a ├ö├ç├┐greener├ö├ç├û process.(7) Berries are also high in phenols such as ellagic acid, an antioxidant that protects the body's cells.(8) The diazonium salt can also be reacted and joined to phenolic groups and amines to give azo compounds.(9) Soy protein is inexpensive and renewable, but it lacks the unique amino acid with phenolic hydroxyl groups that provide adhesive properties.(10) Varnishes may be based on phenolic , alkyd, epoxy or polyurethane resins.(11) Anaerobic metabolism of peptides and proteins by the microflora produces short-chain fatty acids and a series of potentially toxic substances including ammonia, amines, phenols , thiols, and indols 32.(12) The warmer operating temperature of ale yeast encourages a faster, more vigorous fermentation that creates aromatic compounds known as phenols and esters.(13) In general, alkalis do not react with alcohols, but they do react with phenolic compounds.(14) Furfural reacts with phenols , ketones, and esters as an aldehyde; removal of the aldehyde group yields furan, which is converted to tetrahydrofuran, used in the manufacture of nylon.(15) Other natural antimicrobials include the phenolic compounds thymol, found in thyme, oregano and sage, and eugenol, the main flavour ingredient of cloves and allspice.
