What is triethylamine soluble in?

Triethylamine is soluble in water to the extent of 112.4 g/L at 20 °C. It is also miscible in common organic solvents, such as acetone, ethanol, and diethyl ether. Laboratory samples of triethylamine can be purified by distilling from calcium hydride.

Is triethylamine hydrochloride soluble in THF?

Triethylamine hydrochloride is a by-product. My product (polyamide) is soluble in most organic solvents (water, ethanol, methanol, dichlorometane) and insoluble in acetone, DMSO, hexane, THF, dioxane, ethyl acetate… cold water wash decreases the product solubility into the water.

Does triethylamine react with HCl?

You are adding Et3N to a solution that contains HCl as a reaction product. That means there will be HCl vapour above the solution. The Et3N is fairly volatile so there will be Et3N vapour around the addition stream/droplets and this will react with the HCl vapour as it is added to give triethylammonium chloride.

Can triethylamine be used in liquid liquid extraction?

Triethylamine and water are simultaneously removed from solutions in organic solvents, by liquid/liquid extraction with concentrated aqueous solutions of (C 2 H 5) 3 N.H 3 PO 4 which preferably contain free phosphoric acid as well.

How do you remove triethylamine from water?

– Distillation may work if the product or mixture of products are stable in the distillation conditions. If so, vacuum distillation may work fine. The use of co-solvents cal also help and depending on the desired final level of triethylamine you can apply stripping with nitrogen of vapour.

How do you quench triethylamine?

Triethylamine can be dried by stirring it over calcium hydride and then distilling it into a dry flask at atmospheric pressure under nitrogen. Transfer 10-15 mL of triethylamine into a 25-mL round-bottomed flask by dispo pipette.

How do you remove triethylamine from a compound?

If it deprotonated, you can use vaccuum (bp is about 90 degrees) or rinse with a non-polar solvent like ether. If it is protonated, you can wash with water, methanol, ethanol, etc.

Is triethylamine soluble in water?

Physical Properties
Viscosity 0.363 cP at 25°C
Surface tension 20.66 dyn/cm at 20°C
Solubility in water 5.5% at 20°C
Solubility of water in triethylamine 4.6% at 20°C

Is triethylamine miscible with water?

The water–triethylamine system is miscible in all mixing ratios at temperatures less than 18 °C, but separates into two immiscible phases for a wide range of bulk compositions as temperature increases through 19–24 °C.

What makes a good solvent for extraction?

For example, polar solvents such as methanol, ethanol and acetone are miscible with water, thus not suitable for liquid-liquid extraction. Organic solvents with low polarity such as hexanes, toluene, dichloromethane and diethyl ether are usually chosen as the organic extracting solvent.
