M2 PRESSWIRE-August 13, 2019-: Dimethylacetamide
Market Analysis Report 2019 Global Industry Size, Share, Future Growth, Current Statistics, Regional Analysis with Forecast To 2022
After reviewing the literature on the solubility of PSU and PVAc polymers, dimethylacetamide
(DMAc) solvent was selected on the basis of its properties.
The Chemours Company (NYSE: CC), a global chemistry company with market positions in titanium technologies, fluoroproducts and chemical solutions, has announced price increase for all Methylamines, Dimethylformamide, Dimethylacetamide
and Dimethyl Sulfate products sold in North America.
Effective 1 July 2018 or as contracts allow, the new higher price list is all Methylamines, Dimethylformamide (DMF), Dimethylacetamide
(DMAc) and Dimethyl Sulfate (DMS) products sold in North America, added the company.
Polyvinylpyrrolidone (PVP), dimethylacetamide
(DMAc), ammonium persulfate (APS) and a mixture of ultrapure (UP) water (resistivity >18.25 MO cm) and ethanol were used as the non-solvents in the polymer precipitation.
Then N,N- dimethylacetamide
(DMAc) was to form a solution.
To prepare the phase-inverted PVDF membranes, PVDF (534 kDa, Sigma-Aldrich), dimethylacetamide
(DMAC, Sigma-Aldrich), and deionized water were used as polymer, solvent, and nonsolvent, respectively.
The whole polymer is first dissolved in a solvent-like tetrahydrofuran (THF) or dimethylacetamide
The filtered material was sonicated in 100 mL dimethylacetamide
(DMA) for 24 h.
Most identified enhancers can be classified as: alcohols (ethanol, pentanol, benzyl alcohol, lauryl alcohol, propylene glycols and glycerol), fatty acids (oleic acid, linoleic acid, valeric acid and lauric acid), amines (diethanolamine and triethanolamine), esters (isopropyl palmitate, isopropyl myristate and ethyl acetate), amides (1-dodecylazacycloheptane-2-one [AzoneA(r)], urea, dimethylacetamide
, dimethylformamide and pyrrolidone derivatives), hydrocarbons (alkanes and squalene), surfactants (sodium laureate, cetyltrimethylammonium bromide, BrijA(r), TweenA(r) and sodium cholate), terpenes (D-limonene, carvone and anise oil), sulfoxides (dimethyl sulfoxide) and phospholipids (lecithine).
(DMAC), CHPTAC, NaOH, Ti[O.sub.2], and PVA were purchased from Sinopharm Chemical Reagent Co., Ltd.
