hoac

In the investigated systems the " equal medium effect " for HC1 and HOAc was found .

发现在所研究的体系中，盐酸溶液和醋酸溶液具有“等效介质效应”。

All the results show that the proportion of HOAc and TEA doesn ′ t change the essential of chiral separation .

结果表明：冰醋酸和三乙胺的比例并不影响手性分离的实质。

The subtraction method was used to get the precise content of H + of HOAc .

同时，在分析测定酸的重量百分浓度时，利用差减法得到了H＋的准确含量。

The advantage as being the manufacturer Hoac could easily adapt different sizes of trusses perfectly under the walls .

作为生产者的有利条件就是能够不费力的改造不同大小的桁架使之完全与墙契合。

The corrosion of the reactors due to the use of HOAc as solvent and the serious environmental threat posed by bromide have become the major shortcomings .

因HOAc使用而造成的反应器壁的腐蚀以及因溴化物的使用引起的环境污染已成为现代工业生产过程的主要缺点。

Attempt to de benzyl ate of compound 131 with NBS / HOAC was studied and we got compound 133 having no benzyl successfully .

以化合物131为底物，对NBS/HOAC脱苄基的反应进行了研究，顺利制得脱苄基的化合物133。

Without HOAc additive , the retention factors of the amino alcohols were decreased with increase of the amount TEA , separation factors kept constant , except labetalol .

在不加冰醋酸的情况下，除拉贝洛尔外，随着三乙胺浓度的增加，容量因子均减少，分离因子基本不变，分离度减小。

The compound (ⅰ) is hydrolyzed in the presence of Fe_2 ( SO_4 ) _3 · 7H_2O and HOAc to give cinnamic acid (ⅱ) . The both yields are 92 % and 85 % , respectively .

在Fe2（SO4）3·7H2O和HOAc作用下，化合物（Ⅰ）水解生成肉桂酸（Ⅱ），其收率分别为92%和85%。

A novel sol-gel process using inorganic salts as starting materials was successfully developed for preparing nano powders of ferroelectric strontium bismuth tantalate ( SrBi2Ta209 , known as SBT ) with ethylene alcohol as a solvent and acetic acid ( HOAc ) as a catalyst .

以乙二醇为溶剂，醋酸为催化剂，部分无机盐代替醇盐的溶胶-凝胶工艺制备了不同平均晶粒尺寸的纯SrBi2Ta2O9（SBT）纳米粉末，晶相粉末晶粒大小为4-70nm。

Stable solutions were obtained in the mixtures of the precursor solutions with Ca / P ratios of 1.00, 1.50 and 1.67 when the mixtures had HOAC in a HOAC / Ca ratio of 4.After the stable solutions were evaporated , dried gel-like powders could be formed .

当醋酸与钙的摩尔比（HOAC／Ca）为4时，两先驱体分别以Ca／P比为1.00，1.50和1.67混合，均可以获得稳定混合溶液。
