化學試劑與精細化學品的區別?
發布時間: 2016年07月09日 【字體:

  化學試劑屬于精細化學品(精制藥品)范圍。精細化學品系指加工精度高、需用較高技術生產、純度高、生產批量少的化工產品,如試劑、醫藥、香料、合成染料等。但這種說法比較籠統。隨著精細化工的發展,人們需要比較具體而明確的定義。

  精細化學品是具有以下特點的化工產品:

 ?。?1 )品種多,更新換代快。( 2 )產量少,大多以分批方式生產。

 ?。?3 )具有一定的功能性。所謂功能性,是指化學品的分子通過物理作用、化學作用及生物學作用而產生某些功能或效果。例如,紫外線吸收劑、感光材料、增塑劑及其他各種添加劑,是屬于物理作用功能性的精細化學品 ; 抗氧化劑、燃料添加劑等,是屬于化學作用或能性的精細化學品。

 ?。?4 )大多為混合型產品,配方等技術決定產品性能,并以商品名進行銷售。

 ?。?5 )技術密集度高,要求不斷進行新產品的技術開發和應用技術的研究。

 ?。?6 )設備投資規模小,附加產值高。

  化學試劑簡稱試劑。它是一類具有各種標準純度,用于教學、科學研究、分析測試,并可作為某些新興工業所需要的純和特純的功能材料和原料的精細化學品。

  生產精細化學品的產業通稱為精細化學工業。精細化學工業是在化學試劑工業的基礎上發展起來的。所以,國內外著名的試劑公司(廠)通常兼營其他精細化學品,而且其產值往往超過化學試劑的產值。試劑廠商所出版的試劑目錄,實際上也往往是精細化學品目錄。
