6.Appearance soluble in water (2.3% / 40 ℃), easy to dissolve in caustic liquid and common organic solvents.Natural product exists in ylang oil, strawberries, cheese, coffee, cocoa, etc
7.GB 2760-1996 rules to allow the use of edible spices.Use microbicides.Mould inhibitor.In organic synthesis.Use for organic synthesisUse this product is manufacture antioxidant 2, 6 - BHT and rubber protective agent of raw materials, at the same time, the production and medicine TMP and dye can be the important basic raw material of cefoxitin sulfonic acid.Use of cresol is fungicide methyl low phosphorus, insecticide fenvalerate, ether chrysanthemum ester of intermediates, and antioxidant additive 2, 6-2 tertiary butyl - 4 - methyl phenol and intermediates of hydroxy benzaldehyde.Use manufacturing stabilizer (2, 6-264 BHT) and rubber protective agent of raw materials.Can produce phenolic resin and plasticizer in plastic industry.In medicine, used as a disinfectant.In addition, still can make the raw material of dyes and pesticides.Between 1. The production method, a mixture of BHT mother liquor after extracting m-cresol, such as recrystallization by oxalic acid addition process.2. Toluene and sulphonated sulfuric acid neutralization, generated by p-toluene sulfonic acid sodium alkali fusion, acidification, distillation of cresol finished products.In order to get high purity of BHT has two kinds of process: (1) the BHT after rectification and crystallization separation;(2) after the sulfonated p-toluene sulfonic acid, first introduced by cooling, crystallization, filtration, then neutralization, alkali fusion, acidification, rectification and finished products.Nanjing golden YanHua industry corporation development of sulfonated alkali fusion method of mature technology, to produce high purity of cresol, changing process conditions, using the device also can produce m-cresol, o-cresol, phenol, naphthol, etc.
