Introduction

Ethanolamine is an organic compound, also known as 2-aminoethanol. It is a colorless to light yellow liquid with an ammonia odor. Ethanolamine is an important chemical raw material widely used in the preparation of surfactants, emulsifiers, lubricant additives, and so on.

 

Nature:

-Appearance: colorless to light yellow liquid

-Solubility: easily soluble in water and alcohol solvents

-Property: It has alkalinity and can react with acids to form salts

 

Usage:

-Used as raw material for preparing lubricant additives

-Used as a substitute for ammonia and ethylene glycol, applied in the production of coatings, resins, and adhesives

-Used as a buffer and reagent in biochemical research

 

Method:

-Ethanolamine can be prepared by reacting ammonia and ethane oxide

-Or obtained through alcohol amine reaction

 

Security:

-Long term exposure to non ventilated conditions may lead to symptoms such as headache, dizziness, nausea, vomiting, etc

-Appropriate protective measures should be taken, such as wearing gloves, breathable clothing, and eye protection, to reduce exposure risks
