Then recrystallize the thick product with the petroleum ether, the end product obtains its melting point after infrared lamp drying with the melting point detector and compares with the pure Diphenyl carbinol.

粗产物用石油醚重结晶，终产品经红外灯烘干后用熔点测定仪得到其熔点，并与纯品二苯甲醇比较。

Because benzyl alcohol is a common reagent and veratryl alcohol is a special and expensive one, it is very economic to replace veratryl with benzyl alcohol.

鉴于苯甲醇是常用的试剂，用它代替昂贵的藜芦醇在经济上有巨大的效益。

The conversion of alcohols to alkyl halides was investigated using acidic ionic liquid X as halogenating agent, acidic catalyst as well as medium. The reactions of primary alcohols gave very satisfactory conversions and selectivities except for the substrates with lower boiling point,such as n-octanol and benzyl alcohol. They obtained the corresponding halides with almost quantitative yields(95%-100%).The secondary alcohols also gave the corresponding halides with excellent conversions, however, the by-products of dehydration were detected.

伯醇除某些低沸点底物外，都以高转化率(最高达100％)和高选择性(最高达100％)转化为相应的氯代烃、溴代烃和碘代烃，例如正辛醇、苯甲醇，在X中进行卤代反应得到令人满意的结果，无论氯代、溴代还是碘代得到卤代产物的收率一般都很好华东师范大学化学系01级博士学位论文(95十100%)，极少有重排产物及脱水产物被检测出来。

Benzyl alcohol has been associated with a fatal "Gasping Syndrome" in premature infants.

在早产儿中，致命的&呼吸运动失调综合症&和苯甲醇有关。

Adsorption behaviors of benzyl alcohol onto macropore resin JX-101 and influence of inorganic salt on the adsorption were detailedly studied.

研究了水相中苯甲醇在大孔吸附树脂JX-101上的吸附行为及无机盐对吸附的影响。

N-Benzylacryl amide was synthesized using acrylonitrile and benzyl alcohol as raw materials and sulfuric acid as catalyst.

以丙烯腈和苯甲醇为原料，浓硫酸作催化剂，合成了N-苄基丙烯酰胺。

The mixture was concentrated in vacuo to give a reddish oil containing 8 g of 10 and 7 g of benzyl alcohol, according to HPLC analysis.

混合物则集中在真空中作红色油含有8克107、克苯甲醇，根据色谱分析。

In the case of the oxidation of benzyl alcohol, the oxidant, catalyst and the solvent were recovered and reused for 5 times with no decreases of benzyl alcohol conversion and product yield.

氧化剂、催化剂和溶剂均可循环使用，在苯甲醇的氧化中，经5次循环，反应的转化率和收率均保持基本不变。

Now, however, all children continue in "comprehensive" schools, and the eleven-plus determines which courses of study the child will follow.

然而现在，所有的孩子都要在综合学校继续学习，所以这次考试只是决定他们将要学习哪些课程。
