[求助] 文献帮忙翻译下

大神,帮忙翻译一下啊~
Synthesis of 6,6‘-di-O-tosyl Sucrose
Sucrose (10 g, 29.2 mmol) Was dissolved in 50 mL of 0.1
M NaOH. Tosyl chloride (12.3 g, 64.2 mmol) Was dissolved
in 50 mL of toluene and added to the sucrose solution over
30 minutes at 22°. The pH of the reaction Was maintained
betWeen 7 and 8. The 6,6‘-di-O-tosyl sucrose migrates into
the toluene phase Where it is detected by TLC analysis [one
ascent in methyl cyanide/Water (85/15, v/v) on Whatman K5
plates] as a UV-?uorescent compound that also gives a
carbohydrate stain When the TLC plate is dipped into a
solution containing 0.3% (W/v) N-(1-naphthyl)ethylene
diamine and 5% (v/v) concentrated sulfuric acid in
methanol, folloWed by drying and heating at 120° C. for 10
minutes. The toluene phase Was rotary evaporated to give a
syrup containing the product.

谢谢~

6,6' - 二氧-对甲苯磺酰基蔗糖的合成
将蔗糖(10克,29.2毫摩尔)溶解在50毫升0.1摩尔每升的NaOH溶液里。甲苯磺酰氯(12.3 g, 64.2 mmol)溶于甲苯中,再将其加入蔗糖溶液22°保温30min。反应的pH控制在7-8之间。TLC分析【在滤纸K5板乙腈/水(85/15,V / V)的快速膨胀】检测到6,6' - 二氧-对甲苯磺酰基蔗糖已迁移至甲苯相,作为一种荧光化合物,将TLC板浸入含质量-体积百分浓度为3%的N-(1 - 萘基)亚乙基二胺和体积分数5%硫酸的甲醇混合液中对碳水化合物进行染色,然后在120°加热10min进行干燥。甲苯相旋转蒸发得到含产品的糖浆。

有UV的那句怪怪的,我就没管那个。
第一次参与翻译,有不足的地方望海涵,仅供参考。
既然选择了,就坚持下去!
