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%.

 

反應條件(Reaction conditions)

反應溫度 (Reaction Temperature)

100~110℃
