This mixture was distilled with the aid of a dividing wall column into which the mixture was continuously fed. The 1,2-propylene glycol was taken off as intermediate boiler from the side offtake of the column. The objective of the distillation was to purify the 1,2-propylene glycol so as...

propylene oxide is an intermediate of the herbicide metolachlor, and is also an important organic synthesis chemical raw material, propylene glycol, allyl alcohol, propionaldehyde, isopropylamine, synthetic glycerin, organic acids and the like can be produced, and Nonionic Surfactants, wetting agents, ...
EPDM is resistant to polar solvents such as alcohol, glycol, ketone and phosphate ester, acids, alkalis, salts, and fats. However, EPDM does not possess resistance to hydrocarbon oils and solvents. EPDM grades are suitable for use in pipe systems in drinking water applications. The combined ...
Further, for control of 3D printability we incorporate poly(ethylene glycol) diacrylate via radical polymerization, obtaining the poly(maleate-propylene oxide)-lipoate-poly(ethylene oxide) (MPLE) gel as a sec- ond step. The MPLE ink demonstrated high resolution 3D printing scaffold with fidelity ...
An extractive distillation agent consisting essentially of dipropylene glycol is fed to an extractive distillation column used for the distillation of propylene oxide contaminated with water, acetone
The resultant ethylene glycol diacetate solution containing 0.9 mole/l of α-acetoxypropionaldehyde was used. In Control Example 3, the amount of isopropyl acetate to be added to the residual liquid after distillative removal of water from the isopropyl acetate layer was reduced and the resultant ...
