NKC®-1（乙二醇醚）催化劑
NKC®-1（Ethylene oxide to Ethylene glycol ether Catalyst）Catalyst
NKC®-1（乙二醇醚）催化劑用于由乙醇和環氧乙烷制備乙二醇乙醚。
特點：
具有無腐蝕性，無污染的優點；
南開大學研制了新型合成乙二醇乙醚的NKC-1固體酸催化劑，并與天津石油化學公司第三石油化工廠合作進行了60立升釜的中試放大試驗，取得了良好效果；
1984年4月天津市科學技術委員會委托南開大學和天津石化公司對NKC-1催化劑進行了技術鑒定。
鑒定會認為：
1、NKC®-1催化劑可使反應時間縮短2/3，產品收率達到75%左右，比采用BF3催化劑收率增加15%.
2、NKC®-1催化劑活性穩定，對設備無腐蝕，無環境污染。
3、應用NKC®-1催化劑生產的乙二醇乙醚產品質量合格，生產工藝成熟，可以組織工業化試生產。
NKC®-1催化劑獲1985年國家教委科技發明二等獎。
進料比(乙醇/環氧乙烷)=6~8(摩爾);
乙二醇乙醚對環氧乙烷的收率為90%(mol)；
環氧乙烷的單程收率為93%；
乙二醇乙醚的選擇性為97%.
NKC®-1 (glycol ether) catalyst is used to prepare glycol ether from ethanol and ethylene oxide.
Features:
Has the advantages of non-corrosive and non-polluting;
Nankai University developed a new NKC-1 solid acid catalyst for the synthesis of glycol ether, and cooperated with the Third Petrochemical Plant of Tianjin Petrochemical Company to conduct a pilot amplification test of 60 liters of kettle, and achieved good results.;
In April 1984, Tianjin Municipal Science and Technology Commission commissioned Nankai University and Tianjin Petrochemical Company to conduct technical appraisal of the NKC-1 catalyst;
The appraisal will believe that:
1, NKC®-1 catalyst can shorten the reaction time by 2/3, the product yield reaches about 75%, compared with the use of BF3 catalyst yield increased by 15%.
2, NKC®-1 catalyst activity is stable, no corrosion to the equipment, no environmental pollution.
3. The quality of ethylene glycol ether produced by NKC-1 catalyst is qualified, the production process is mature, and industrial trial production can be organized.
The NKC®-1 catalyst won the second prize of the National Education Commission for Scientific and Technological Invention in 1985.
Feed ratio (ethanol/ethylene oxide) = 6 to 8 (molar);
The yield of ethylene glycol ether to ethylene oxide is 90% (mol);
Ethylene oxide yielded 93% in one pass;
The selectivity of ethylene glycol ether is 97%.
