Nevertheless, this approach was constrained by the stringent requirements for hydrogen bond acceptors, which required that the organic salt should form DES with the target solute and not dissolved with the raffinate [41]. Another method was that the DESs were directly used as extractants to ...
salt extractionA novel process which can purify the organic solvents from their azeotropes with water is proposed. In this process, water can be drained off both from bottom and overhead of tower at the same time, and the organic solvent is concentrated in the tower and accumulated in the ...
2b). Subsequently we tested the influence of other biomolecules and salt concentration on droplet formation (Fig. 2c). Addition of RNA to the PEG-8000 containing buffer enhanced SMNDC1’s droplet formation while high NaCl concentrations prevented droplet formation. Digestion of RNA by RNase led ...
A simple and basic way to separate water and oil is to put the liquid into a container and begin slowly draining the water into another container. Since oil naturally sits on top of water, no matter where the spout is on the jug, the oil will always be on the top. The best container...

A process and extractant composition for extracting acids not available for EP075060of corresponding document:The invention provides a process for the recovery of a water-soluble carboxylic or mineral acid having a pKa higher than 2 from an aqueous feed solution containing the acid or a salt th...
The traditional production manner of making stichopus japonicus naturally fall with salt is at the cost of 9-10 yuan for each ton of water and 20-24 yuan for potassium chloride, but the cost of the seedling separating agent is 5-8 yuan. The cultivation cost is reduced. When being used, ...
e. first to distill off the ingredients which are more volatile than acetic acid and then to distill acetic acid from the residual mixture. EXPERIMENT A Acetic acid concentrate which had been prepared by treating pyroligneous acid in known manner to remove most of the water (i. e. the ...
1. A method for recovering HF from a mixture comprising HF and a halogenated hydrocarbon comprising contacting the mixture with an ionic liquid, wherein the ionic liquid is a salt and wherein the anion of the ionic liquid is Cl−, F−, and (HF)nF−, wherein n is a positive numbe...
1. A method for preventing scaling of ultrafiltration or nanofiltration membranes in a one-step membrane process of separating an organic compound or a biomass and a soluble inorganic salt from an aqueous feed mixture, which mixture further comprises one or more inorganic compounds, that cause scali...
