What is Coconut Diethanolamine?

Diethanolamine, also referred to as bishydroxyethylamine, 2,2′-iminodiethanol, is a white crystal or colorless fluid with strong hygroscopicity. It is quickly soluble in water, methanol, ethanol, acetone as well as benzene. The solubility (g/100g) in benzene at 25 ° C is 4.2 and 0.8 in ether. The “Benfil” remedy utilized in the ammonia synthesis industry is generally made up of this item; it is also made use of as an emulsifier, lubricating substances, hair shampoos, thickeners, etc; organic synthesis intermediates, utilized in the production of detergent raw materials, preservatives and everyday chemical products (such as surfactants); synthesis of morpholine.

Coconut Diethanolamine Uses

  1. Coconut Diethanolamine Utilized as thickener, foam improver in shampoos as well as light cleaning agents, as conditioner in man-made fiber along with leather manufacturing. Diethanolamine Sigma reacts with 70% sulfuric acid to dry out and cyclize to create morpholine (ie, 1,4-oxazacyclohexane). The fat salts of morpholine can be made use of as chemicals. Morpholine can also be utilized to generate the central inhibitor Fulco. dealt with or as a solvent. Diethanolamine is used in logical chemistry as a reagent as well as a set fluid for gas chromatography to uniquely maintain and divide alcohols, diols, amines, pyridines, quinolines, piperazines, thiols, thioethers as well as water.
  2. Coconut Diethanolamine is an essential rust prevention that can be made use of in main home heating central heating boiler water therapy, coolant for car engines, drilling and also lowering oils, as well as other kinds of fueling oil oils. It is additionally used as an absorbent for cleansing acid gas in gas. Made use of as an emulsifier in numerous cosmetics and likewise pharmaceuticals. It is used as a lubricating substance in the fabric market, as a wetting agent, a softener along with different other natural artificial raw materials.
  3. Coconut Diethanolamine Benefited from as acid absorbent, plasticizer, conditioner, emulsifier, and so on in adhesives. It is likewise used as a soaking up for acid gases (such as hydrogen sulfide, carbon dioxide, and also extra) in oil gas, gas as well as various other gases. It is the raw thing for the synthesis of medicines, pesticides, shade intermediates along with surfactants. It is made use of as an emulsifier for oils and also waxes, as well as a conditioner for natural leather along with artificial fibers under acidic problems. Made use of as a thickener along with foam improver in shampoos in addition to light cleansing representatives. Furthermore utilized as detergent, lubricating substance, brightener and engine piston ash remover.
  4. Made use of as a complexing representative for silver, cadmium, lead, along with zinc plating.
  5. Coconut DiethanolamineUsed as logical reagents, acid gas absorbents, conditioners and lubricating substances, and also in all-natural synthesis.

A New Synthetic Process of Coconut Diethanolamine

At present, the production process route of diolamine in the world is mainly epoxy dialkyl ammonolysis method, and the adopted processes are mainly tubular reaction and rectification separation process. The process uses ammonia and dioxane as raw materials to synthesize MEA, DEA, TEA and some by-products in a tubular reactor (or tower reactor), and the mixture is separated by rectification to obtain high-purity products. Patent 200910098497 reports a short-flow process for the production of diol amines, using liquid ammonia and dioxane as raw materials to produce diol amines in the presence of a small amount of water catalyst. Patent 96100557 reports an anhydrous tubular reaction method for the production of diol amines. This process is also to pre-mix liquid phase epoxy dioxane and liquid ammonia at a certain proportion at low temperature, send them into a tubular reactor for high-pressure reaction, and then undergo a step-down process. Excess ammonia is distilled off and recovered. Both patent 90103426 and patent 20091098498 are related to the production method of Coconut Diethanolamine by liquid-liquid tube reaction.

There are several technical difficulties in the existing glycol amine synthesis process. (1) the boiling point of glycol amine is very high (MEA: 170 ° C, DEA: 268.8 ° C, TEA: 360 ° C), product rectification needs to be carried out under high vacuum, and system energy consumption is very high; (2) two Alcohol amine synthesis reaction is a strong exothermic reaction (the exothermic heat per mole of dioxane ring-opening reaction is 92 kj), the existing process must remove a large amount of reaction heat from the reactor in time, and removing the reaction heat not only affects the energy utilization efficiency (3) because the diethanolamine in the glycol amine product is the intermediate product of a series of reactions, it is difficult to reach high diethanolamine in the existing synthetic technology Selectivity (no more than 30%), thereby limiting the improvement of its output (diethanolamine is the product with the largest consumption in the three kinds of glycolamine). Therefore, if the selectivity of diethanolamine can be significantly improved in the process of synthesizing Coconut Diethanolamine, this will be very beneficial to increasing this product output and reducing subsequent separation costs.

Specific Implementation of Coconut Diethanolamine

1) Using dioxane and 90% ammonia water as raw materials, at 3.0MPa, 50°C, and under the condition that the molar ratio of ammonia water and dioxane is 10:1, first react in a tubular reactor, Until dioxane conversion is complete, synthetic diol amine mixed product, product composition (by mole fraction) is: MEA54.25%, DEA27.59%, TEA18.16%;

2) the mixed product obtained in step 1) is first passed through the flash tank multi-stage flash decompression, and 20 ~ 30% of unreacted ammonia is separated, and then enters the ammonia distillation tower to steam the remaining ammonia, and the ammonia distillation tower The product (by mole fraction) that obtains at the bottom of the tower is: MEA71.51%, DEA18.18%, H O2.33% and TEA7.98%;

3) Step 2) The product obtained at the bottom of the ammonia distillation tower enters the upper part of the reactive distillation tower, and simultaneously introduces dioxane from the middle part of the reactive distillation tower, and the feed molar ratio of dioxane to the bottom product of the ammonia distillation tower is It is 1: 1, and two strands of materials carry out chemical reaction and product separation simultaneously in reactive distillation tower, and the operating pressure of reactive distillation tower is 0.5atm, and reaction temperature is 100 ℃, and reboil ratio is 8.0, and reactive distillation Water is produced at the top of the tower, and high-purity diethanolamine products are produced at the bottom of the tower. In terms of mole fractions, the product consists of DEA 82.36%, TEA 17.64%.
