邻苯二酚是氨基甲酸酯类农药克百威(呋喃丹)、残杀威、乙霉素的重要中间体,也是生产香兰素、胡椒醛等香料的原料,还可以生产对叔丁基邻苯二酚阻聚剂、抗氧剂及其他精细化学品,我国年需求量在8000～9000吨左右,一直主要依赖进口,国内自给率仅10%左右。目前世界上只有法国、意大利、日本的几家公司能采用苯酚羟基化的先进技术生产,但都不对外转让技术,其产品技术转让还带有苛刻条件,严重制约了我国下游相关产品的发展。
Catechol is a carbamate pesticide carbofuran (carbofuran), propoxur, ethamectin important intermediates, but also the production of vanillin, piperonal and other spices raw materials, but also can produce p-tert-butyl o-benzene two Phenol polymerization inhibitors, antioxidants and other fine chemicals, China’s annual demand of 8,000 to 9,000 tons, has been mainly dependent on imports, the domestic self-sufficiency rate of only about 10%. At present, only France, Italy and Japan can use the advanced technology of phenol hydroxylation. However, they all do not transfer the technology to outside world, and the technology transfer of their products is accompanied by harsh conditions, which severely restrict the development of downstream products in China.
