Dimethyl formamide (DMF) and 1,4-dioxane were obtained from Baotelai Chemicals (Xi'an, China).
Figure 7 shows an overlay of simulated and experimental cyclic voltammogram of dicyano(fluoren-9-ylidene)methane: B at vitreous carbon cathode in
dimethyl formamide containing 0.1 M tetra-n-butyl ammonium iodide in the presence of an equivalent of phosphonium salt (PhCH:CHCH2P+Ph3NO3-), also exhibit formation of dianion which is sufficiently basic enough, stronger base than its bromo derivative, to accept a proton from the added phosphonium salt.
Control mice received vehicle only (1%
dimethyl formamide in water for injection).
Instead of buying methanol, which goes into the manufacturing of its downstream products, the company will produce it at a lower cost, enabling it to become more competitive in international markets The company, formerly Saudi Formaldehyde Chemical Company, will produce from its latest expansion the following products: methanol, carbon monoxide, acetaldehyde, methylamines (MA),
dimethyl formamide (DMF), pentaerythritol and formaldehyde.
Triton X-100 was from Bio-Rad;
dimethyl formamide (DMF), acetone, methanol, and acetonitrile (HPLC grade) were from Merck.
Imagine turning chloroform into
dimethyl formamide with carbon dioxide as the only reagent, and then reversing the process with nitrogen gas.
Solvent Resource Management, Sunderland: The 65-employee company completed a major project to recover
dimethyl formamide (DMF) from a customer's waste stream that was going to landfill.
Solutia Austria GmbH has been granted a patent for a coating composition comprising a condensation product of a carboxyl group-containing resin having a Staudinger Index, measured in
dimethyl formamide as a solvent, of from 4.0-12 [cm.sup.3]/g, and a hydroxyl group-containing a resin having a Staudinger Index, measured in
dimethyl formamide as a solvent of from 8-13 c[m.sup.3]/g, and a curing agent that becomes active only at an elevated temperature of at least 80[degrees]C.
Many alternative soaking solvents used in the application are based on solvents such as n-methyl pyrrolidone (NMP), dibasic ester (DBE) and
dimethyl formamide (DMF), according to the company.
Dimethyl formamide, on the other hand, rapidly produces the same biphenyls, but leaves them linked as an undesirable, sludgelike polymer.
The product was dried under vacuum at 60 AdegC and purified by
dimethyl formamide. A general synthesis procedure is shown in Scheme 2 and the corresponding diazo (A) and coupling components (B) are all listed in Table-1.
