UseApplication (2S)-2-methoxy-1-propanol, also known as propylene glycol methyl ether (PM), is a solvent with excellent performance and low toxicity, with strong solubility and low volatility, high flash point, mild odor and other characteristics. It is one of the important products of propylene glycol ether series compounds, which is widely used in coatings, printing and dyeing, pesticide and other industries. At the same time, it can also be used as fuel antifreeze, detergent, extractant and organic synthesis intermediate. The molecular structure, physical and chemical properties of propylene glycol monomethyl ether are similar to that of ethylene glycol ether, so it is considered to be an ideal substitute for ethylene glycol ethers with great toxicity.

CN201710264882.6

application date:

2017-04-21

Public/Announcement Number:

CN107032986A

Public/announcement date:

2017.08.11

applicant (patent):

Jiangsu Tianyin Chemical Co., Ltd.

inventor:

Qin Yisan , Qin Xiaoqi , Yang Jianguo , Zhang Xuejun , Chen Rongfu

National and provincial code:

CN320282

Abstract:

The invention discloses a method for synthesizing 2 methoxy 1 propanol acetate catalyzed by an acidic ionic liquid, which is characterized in that 2 methoxy 1 propanol and acetic acid are used as raw materials, 2 methoxy 1 propanol acetate was synthesized by esterification dehydration method under the action of acidic ionic liquid catalyst 1 butyl 3 methylimidazolium hydrogen sulfate and cyclohexane dehydrating agent, the amount of catalyst is 0.28% of the mass of 2 methoxy 1 propanol and acetic acid; The molar ratio of 2 methoxy 1 propanol and acetic acid is 1:13; The esterification reaction temperature is 75150 ℃, the water generated in the esterification reaction is removed by azeotropic distillation with cyclohexane; The product of the esterification reaction is distilled to obtain 2 methoxy 1 propanol acetate, after rectification, the kettle liquid contains catalyst and part of 2 methoxy 1 propanol acetate for recycling. The method has high catalyst activity, good stability, low corrosion to equipment, and the catalyst can be recycled.

applicant (patent):

Changzhou Chinese Chemical Co., Ltd.

inventor:

Chen Wenyang , Chen Wenfei , Li Kang

National and provincial code:

CN320411

Abstract:

The present invention discloses a method for preparing (S)-( )-2-methoxymethoxy-1-propanol, which has the following steps: ① adding an organic solvent and (S)-( )-2-methoxymethoxy-1-propionic acid is added to the reaction apparatus and stirred, then cooled to 0 °c ~ 10 °c, after adding, heat up to 15 ℃ ~ 40 ℃ and react for 1H ~ 3H to obtain mixed material; ② cool the mixed material obtained in step 1 to -20 ℃ ~ 10 ℃, the solvate of boron trifluoride was added dropwise and the reduction reaction was carried out for 5h to 10H. After the reaction was finished, (S)-( )-2-methoxymethoxy-1-propanol was obtained by post-treatment. The method of the invention has mild reaction conditions, does not need special low-temperature equipment, and is simple in operation, safe and reliable. And high yield, high purity, low cost.
