What is Monoethanolamine?

Monoethanolamine is a general term for monoethanolamine (MEA), diethanolamine (DEA), and triethanolamine (TBA). As one of the important derivatives of ethylene oxide, it is the most practical product among amino alcohols, and its output accounts for 90% to 95% of the total output of amino alcohols. There are nitrogen atoms and hydroxyl groups in the ethanolamine molecule, so it has the chemical properties of both amine and alcohol.

At present, the most important application of Monoethanolamine products is the production of surfactants, and they are also used in textile chemicals, gas purifiers, cement coagulants, petroleum additives, leather softeners, lubricating oil anti-corrosion agents, anti-coke additives, etc.

Monoethanolamine Uses

  1. Monoethanolamine is made use of as a fixed liquid as well as solvent for gas chromatography.
  2. Monoethanolamine is a handling aid for the food industry that is enabled to be used in GB 2760-96.
  3. Monoethanolamine is utilized in the prep work of different pharmaceutical substances and also inhibitors. Utilizing ethanolamine as raw material to synthesize substituted carboxyl compounds has strong antitumor activity. It is likewise used in the synthesis of aminoquinolones with anti-plasmodium task.
  4. Monoethanolamine is made use of to remove acid gas in gas as well as oil gas, and to manufacture non-ionic detergents, emulsifiers, and so on.
  5. Monoethanolamine is also commonly used as a filtration fluid for removing acidic parts from different gases (such as gas). Alkanolamides created from ethanolamines and also fats work foam builders. Ethanolamine is additionally an intermediate of emulsifiers, used in the fabric sector as antistatic representatives, anti-moth representatives, as well as cleaning agents. Piperazine hexahydrate can be acquired by cyclization and neutralization of ethanolamine hydrochloride, as well as piperazine can be made use of as an anthelmintic in the form of its phosphate or citrate.
  6. Monoethanolamine is generally made use of as a plasticizer, vulcanizing representative, accelerator and also frothing representative for synthetic materials as well as rubbers, as well as intermediates for chemicals, medicines as well as dyes. It is likewise a basic material for artificial detergents, emulsifiers for cosmetics, etc. Textile sector as printing and dyeing brightener, antistatic agent, anti-moth agent, detergent. It can additionally be made use of as a carbon dioxide absorber, ink additive, and petroleum additive. Monoethanolamine is widely made use of as a purification fluid for removing acidic components from various gases such as natural gas. Piperazine hexahydrate can be obtained by cyclization as well as neutralization of ethanolamine hydrochloride. One ethanolamine hydrochloride is chlorinated by thionyl chloride, and afterwards replaced by sodium thiosulfate to acquire β-aminoethyl thiosulfate. This is a dye intermediate made use of in the manufacturing of polycondensed turquoise blue 13G. The response of monoethanolamine and carbon disulfide can create the intermediate thiothiazoline which is utilized in the rubber and pharmaceutical sectors.

Production Method of Monoethanolamine

  • Monoethanolamine can be prepared by the reaction of ammonia as well as ethylene oxide.
    Ethylene oxide, ammonia option and circulating ammonia become part of a stainless-steel activator with a cooling device inside. The response temperature is 30-40 ° C and the reaction pressure is 0.7-3MPa. The response product goes into the deammonization tower, as well as the eliminated ammonia is gone back to the ammonia absorber to prepare an ammonia option, as well as the bottom item is vaporized, focused, dried out as well as dehydrated to obtain crude ethanolamine. Monoethanolamine, diethanolamine and triethanolamine are distilled out individually by vacuum cleaner distillation, the pureness can reach 98%-99%, the conversion price of ethylene oxide is close to 100%, and the yield of Monoethanolamine has to do with 95%. In addition, there is still a percentage of by-product polyether, as well as including a small amount of co2 to the raw material can minimize the generation of byproducts.
