butanol

MethodsExpanding reagent: butanol-water-acetic acid glacial(5∶2∶1),stationary phase: G silicon gel and colorate reagent: dissolve ninhydrin in acetone.

方法以正丁--醋酸(5∶2∶1)为展开剂,在硅胶G薄层板上展开,用茚三的溶液显色后观察。

In this paper we studied the simple history,principle,process and selective method of carrier and medium of production of acetone and butanol with fermentive method of clostridium aceto-butylicum.

本文研究了丁菌发酵法生和丁的简史、原理、过程,以及载体和培养基的选择方法。

The oil absorption value test clarifies that the surface oleophilic character of MnCO3 received on the condition that butanol, CTAB bulk ratio of 1:4 have been well improved.

吸油值测定结果表明：经正丁与CTAB体积比为1:4体系得到的碳酸锰粉表面亲油性能得到明显改善。

To continue the natural identified chemical after that,we have found that 4-(4-hydroxyphenyl)-2-butanol(Rhododendrol:RD)inhibited the melanin synthesis more than Arbutin did.

我们在探索天然化合物的过程中,发现4-(4-羟苯基)-2-丁(杜鹃:以下简称RD)抑制黑色素合成的作用比熊果苷更强。
