Thereare no universally accepted definitions of bulk,fine,and specialtychemicals,nor are theseclassifications based on any intrinsic properties.For example,a substance thatis currently been classified as a fine chemical at an earlier stage in itsdevelopment.
Chemicals are divided onthe basis of volume and character.Bulk chemicals,or commodities,are producedin large quantities and sold on the basis of an industry specification.There isessentially no difference in the product from different suppliers.Typicalexamples would be acetone,ethylene oxide,and phenol.Pseudo commodities arealso made in large quantities but are sold on the basis of their performance.Inmany cases the product is formulated and properties can differ from onesupplier to another.Examples include large volumepolymers,surfactants,paints,etc

对于大宗化学品,优良化学品,和专用的化学品并没有一个被普遍接受的定义,这些分类也不基于任何内在属性.例如,一种物质可能在其初期发展阶段就被归类为优良化学品了.化学物质是按体积和性质来分类的.大宗化学品或散装商品都是大批量生产的,并且按照工业标准规格销售的.基本上不,同的供应商的产品是没有差别的.典型的例子是丙酮、环氧乙烷和苯酚.伪商品也在大批量生产,但销售的数量根据他们的效果而定的.在许多情况下,产品的制定和属性可以从一个供应商到另一个供应商而有所不同.比如大量聚合物、表面活性剂、油漆等
