Two types of "Cleaning and Shining" difunctional paste detergents have been successfully synthesized from special China clay.
本工作以特定白瓷土为原料,成功合成了两种兼有清洁、上光功能的清洁膏。
Such a process is particularly useful in the production of difunctional monomers and intermediates in the synthesis of adipic acid.
这样一种方法对于制备双官能单体和合成己二酸的中间体特别有用。
The invention discloses soluble VEGFR difunctional fusion receptors, a preparation method thereof and the application thereof to antineoplastic preparation.
