The polar solvents can be further be subdivided into two categories:The polar aprotic solvents are ...
1.Dimethyl sulfoxide (CAS NO. 67-68-5) is an important polar aprotic solvent. 2.It is widely used to strip photoresist in TFT-LCD 'flat panel' displays and advanced packaging applications (such as wafer-level packaging / solder bump patterning). 3.It also used i...
There are 3 types of solvents commonly encountered: nonpolar, polar aprotic, and polar protic.(There ain’t such a thing as a non-polar protic solvent). 4. Nonpolar Solvents Have Little To No Dipole Moment These solvents have low dielectric constants (<5) and are not good solvents for cha...
Polyarylene sulphide-sulphonic acids which are soluble in polar aprotic solvents are new. Also claimed is the prepn. of the acids, comprising completely dissolving the polyarylene sulphide in chloro sulphonic acid, opt. adding oleum or acetic anhydride, and then precipitating the prod. in an aq...
3.09.3.3.5Solvent effects It has also been noted thatpolar aprotic solventscan promote activity. These reactions are thought to be fast relative to competingradical polymerization. Suddabyet al.58described the effect of CTAs inN′,N-dimethyl formamide (DMF) as catalytic inhibition.DMFforms a compl...

Propylene Carbonate is a propylene glycol derived from carbonate ester, known as a VOC-exempt solvent aprotic and polar solvent. Along with high boiling and flash points and a mild ether-like odor, propylene carbonate is also non-corrosive. Learn details of the Advances in Propylene Carbonate Mar...
(a) from 1% to 20% by volume of an aprotic polar solvent selected from among dimethylsulfoxide, dimethylformamide, N-methylpyrrolidone, N-methylmorpholine, γ-butyrolactone, acetonitrile and mixtures thereof; and (b) from 99% to 80% by volume of an ether selected from among methyltert-butyl...
2) polar aprotic solvent 极性非质子溶剂 1. The application of ultrasonic radiation and polar aprotic solvent in the synthesis of dialkyl thiourea with NH_2C(=S)NH_2 and RBr was studied in this paper for the first time. 本文首次报道了超声波辐射和极性非质子溶剂在硫脲与溴代烷反应合成二...
