NKC^®-1（乙二醇醚）催化剂

NKC^®-1（Ethylene oxide to Ethylene glycol ether Catalyst）Catalyst

NKC^®-1（乙二醇醚）催化剂用于由乙醇和环氧乙烷制备乙二醇乙醚。

特点：

具有无腐蚀性，无污染的优点；

南开大学研制了新型合成乙二醇乙醚的NKC-1固体酸催化剂，并与天津石油化学公司第三石油化工厂合作进行了60立升釜的中试放大试验，取得了良好效果；

1984年4月天津市科学技术委员会委托南开大学和天津石化公司对NKC-1催化剂进行了技术鉴定。

鉴定会认为：
1、NKC^®-1催化剂可使反应时间缩短2/3，产品收率达到75%左右，比采用BF3催化剂收率增加15%.
2、NKC^®-1催化剂活性稳定，对设备无腐蚀，无环境污染。 
3、应用NKC^®-1催化剂生产的乙二醇乙醚产品质量合格，生产工艺成熟，可以组织工业化试生产。

NKC^®-1催化剂获1985年国家教委科技发明二等奖。

进料比(乙醇/环氧乙烷)=6~8(摩尔);

乙二醇乙醚对环氧乙烷的收率为90%(mol)；

环氧乙烷的单程收率为93%；

乙二醇乙醚的选择性为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%.
