精细化学品化学合成始于1856年,由Perkin第一次合成出精细化学品苯胺紫。目前世界上人工合成化合物约1000万种以上。专用化学品是化工产品精细化后的最终产品,专用化技术是精细化工最重要的标志,专用化学品的附加值要比精细化学品高得多,可以通过多种多样的专用化技术,如:分离纯化、复配增效和剂型改造等技术。现代精细化工是生产精细化学品和专用化学品工业的总称;由于初级石油化工产品随着加工深度的不断延伸,附加值不断提高,发达国家
The chemical synthesis of fine chemicals began in 1856, when Perkin first synthesized the fine chemicals aniline violet. At present, there are more than 10 million synthetic compounds in the world. Special chemicals are the final products after refinement of chemical products. Specialized technology is the most important symbol of fine chemicals. The added value of specialty chemicals is much higher than that of fine chemicals, and can be achieved through a variety of specialized technologies, such as : Separation, purification, synergism and modification of dosage forms. Modern fine chemical industry is the general term for the production of fine chemicals and specialty chemicals; due to the continuous extension of the processing of primary petrochemical products, the added value continues to increase.
