Basing on the practical experience and processing principle , the optimization of producing process , in which the butyl alcohol is abstracted from the water phase by the azeotropic distillation of the partly and mutually dissolved , is studied in this paper by utilizing the properties of the azeotropic distillation of the partly and mutually dissolved system of butyl alcohol and water , from the some questions such as rearranging of the equipments , dissolving with sodium hydroxide , treating of the wasted water , separating water and so on 摘要結合實踐經驗和工藝原理,利用丁醇和水組成的部分互溶系統的共沸特性,對從青霉素類結晶母液中提純丁醇的生產工藝進行了分析研究,從設備布局、堿洗、廢液處理和分水滯后等方面進行了優化處理。

Studied the liquid - phase synthesis of butyl acetate from n - butyl alcohol and acetic acid using the supported heteropoly blue as catalyst . examed several factors imposing on esterification . the results revealed : using this catalyst , the reactions conversion percentage reaches nearly 100 % , product yield is 98 . 9 % , selectivity is 98 . 9 % . reusing it 10 times , the efficiency is still well . in addition , using this catalyst , the reactions temperature is mild , the reaction time is short and the equipment hasnt any erosion . furthermore , there is no “ threewastesdischarge 對以負載型雜多藍為催化劑的乙酸與正丁醇的液相酯化反應進行了研究.考察了影響酯化反應的因素.結果表明:以負載型雜多藍為催化劑,酯化反應轉化率接近100 % ,收率可達98 . 9 % ,選擇性為98 . 9 % ,重復使用10次催化效果仍好.該催化劑還有反應條件溫和、反應時間短、對設備無腐蝕、無三廢排放等優點

It is discovered that existence of small amount of n - butyl alcohol in mesoporous zeolite synthesis system can not only modify ordered degree of formation of mesoporous zeolite , which improves hydrothermal stability of it , but also help to attain much smaller , nearly nanometer , grain of mesoporous zeolite 研究發現,少量正丁醇的存在能改善介孔分子篩形成過程的有序度,并使其水熱穩定性得到提高,同時合成產物的粒度更小,趨近納米顆粒。

As to the solvent , hexane and butvul acetate is discussed and former is more suitable for biotransformation . among seven kinds of energy source : menthok alcohok glycok glycerou 1 - hexanok butyl alcohol octyl alcohol , glycol is selected as energy source , so hexane - glycol is used as reaction system 從生物相容性和有利于轉化的角度對兩種溶劑,正己烷和乙酸丁酯進行了比較,確定了正己烷?憶二醇為該模型反應的溶劑體系。

In this paper , glycidyl ether , which was high epoxide value and low viscosity , was synthesized from 2 - trimethylene glycol , epichlorohydrin and the normal butyl alcohol by phase transfer catalyst based on the orthogonal experiment design 摘要采用1 , 2 -丙二醇、正丁醇和環氧氯丙烷為原料,在相轉移催化劑的作用下反應,通過正交實驗合成了的高環氧值、低粘度的混合醇縮水甘油醚。

This paper made a research on effects of n - butyl alcohol as auxiliary in traditional mesoporous zeolite synthesis system 摘要研究了在傳統的水體系下,將少量正丁醇引入介孔分子篩合成體體系做助劑對介孔分子篩合成及其物化性能帶來的影響。
