設計總說明 醇醚己基磺基琥珀酸雙酯鈉是第二次世界大戰后出現的一類新型的陰離子表面活性劑,它能與多種表面活性劑配合使用,產生良好的協同效應,廣泛應用于洗滌、化妝品等日化行業及石油開采、烯烴單體乳液聚合,金屬清洗、紡織印染、感光材料等工業領域。近幾年來,隨著消費者對洗滌劑的性能要求日趨強烈,特別是其洗滌性能已受到廣泛關注,因而在日用化學品方面的應用顯示出廣闊的前景,對這類表面活性劑進行深入而廣泛的研究是極有必要的。 現有三種成熟的合成醇醚己基磺基琥珀酸雙酯鈉的工藝方法,分別為采用控制酯化率和非外加相轉移催化劑在常壓進行反應法,采用馬來酸酐經單酯化,O-烷基化,選擇性磺化反應法以及采用非外加相轉移催化劑在敞開體系中進行反應的方法。經過反復比較能耗,經濟,設備等方面因素,本設計最終采用非外加相轉移催化劑在敞開體系中進行反應的方法合成醇醚己基磺基琥珀酸雙酯鈉, 并以此工藝路線為基準開發并轉化為實際工業生產過程。 采用市場中現有方便易得的工藝生產所需原料,確定物料的來源,價格和規格,確定每種原料,中間產物以及最終成品的物理性質。經過對醇醚己基磺基琥珀酸雙酯鈉工藝研究,確定最佳工藝條件:AEO-3、馬來酸酐以摩爾比例1.00:1.10,于110℃下單酯化反應2.0h,得到產率為99%的單酯化產物; 單酯化產物、正己醇以摩爾比例1: 3.00,于160℃下雙酯化反應2.5h,得到產率為95%的雙酯化產物;雙酯化產物、亞硫酸氫鈉以摩爾比例1:1.05,于150℃下磺化反應2.5h,得到產率為99%的產物。開發一個新的工業生產工藝過程來合成醇醚己基磺基琥珀酸雙酯鈉。根據工藝流程進行物料和能量衡算。進而根據物料衡算以及能量衡算,選擇并確定生產過程使用的設備型號。 根據國家對化工企業生產的一系列要求,如: 生產過程危險品和有害因素分類與代碼(GB/T13816-1992), 常用危險化學的分類標準(GB13690-1992), 壓力容器中化學介質典型危害和爆炸危險程度分類(HGJ43-1991), 工廠防火規定(GBJ16-1987),污水綜合排放規定(GBJ8978), 工藝系統設備布置設計規定(HG20570), 化工裝置管道布置設計規定(HG/T20549),開發并設計適用于實際生產的工藝流程和設備布置圖。 36111

Design specification Sodium hexyl alkyl polyoxyethene(3) ether sulfosuccinate  is a new type of anion table surfactant after World War II,  which could be used with many kinds of surfactants in conjunction,  then generate good synergy  and  widely used in detergent,  cosmetics and  other daily chemical industry and petroleum exploitation,  olefin monomer polymerization,  metal cleaning, textile dyeing, photosensitive materials, and other industrial fields. The determination of the optimum choice and optimization of the production process, material balance and energy balance of the ethylene oxide, esterification, sulfonation, the selection and design the main equipment oxidation reactor, the esterification of vertical reactor, sulfonation reactor had all be made. In the recent years, with the large demand of detergent among consumers, especially the quality of the detergent, it is very necessary to study sodium dodecanol polyoxyethylene ether succinate sulfonate deeply. In the initial design,  there are three process of synthesis method to surface sodium hexyl alkyl polyoxyethene(3) ether sulfosuccinate.There are esterification rate and the non-use of controlled phase transfer catalyst at atmospheric pressure plus the reaction,maleic anhydride by monoesterfication,O-alkylation and selective sulfonation, carrying out in unclosed system and without any extra phase transfer catalyst after repeated comparison and validation,sodium hexyl alkyl polyoxyethene(3) ether sulfosuccinate is synthesized using a new simple method carried out in unclosed system and without any extra phase transfer catalyst. According to the craft route benchmark development and translated into actual industrial production process. Searching in the market now, I adopte to process the raw material for production, to determine the price of material sources, and specifications. Determine each physical property data of raw materials and finished products. And in sodium hexyl alkyl polyoxyethene(3) ether sulfosuccinate process research is used to determine the optimum process parameters: esterification at 110℃  for 2.5h with a 1.10:1.00molar ratio between maleic anhydride and alkyl polyoxyethene (3)and the yield of monoester can be 99%;diesterfcation at 160℃for 2.0h with 1.00:3.00 molar ratio between maleic anhydride and hexanol and the yield can be 95%; sulfonation at a heating medium temperature of 150℃for 2.5h with a 1.00:1.05molar ratio between maleic anhydride and  sodium hydrosulfite.To develop a sodium hexyl alkyl polyoxyethene(3) ether sulfosuccinate new acetate used in industrial production process. And the material and energy balance. And then according to the energy balance equipment used to determine the production process models. According to the state of a series,  of chemical enterprise production,for example: Production process dangerous material and harmful factor classification and code(GB/T13 816-1992),  Commonly used dangerous chemistry classified standard(GB13690-1992),  Inpre- ssure vessel chemistry medium model harm and explosion hazard degree  classifi- cation(HGJ43-1991),  Factory fire protection  stipulation  (GBJ16-1987),  the sewage synthesisdischarges the stipulation (GBJ8978),  Craft system arrangement of equipment design stipulation (HG20570), Chemical installment piping arrangement design  stipulation  (HG/T20 549). Development and design is suitable for the actual production process flow and equipment layout. 年產600噸醇醚己基磺基琥珀酸混合雙酯鈉生產車間的工藝設計+圖紙:http://www.aftnzs.live/huaxue/20190609/34442.html
