Methane-, sodium

Adams and Schoenherr [29] achieved most of these benchmarks by formulating an adhesive consisting of a 40 wt % solids solution of kraft lignin in phenol-methanal-sodium hydroxide. This fluid had a viscosity of 10 Pa/s and thus was a very thick and energy-consuming adhesive to spread. However, when this binder was used in the manufacture of three ply panels of Douglas...

Claisen reaction Condensation of an aldehyde with another aldehyde or a ketone in the presence of sodium hydroxide with the elimination of water. Thus benzaldehyde and methanal give cinnamic aldehyde, PhCH CH-CHO. 

Docusate Calcium. Dioctyl calcium sulfosuccinate [128-49-4] (calcium salt of l,4-bis(2-ethylhexyl)ester butanedioic acid) (11) is a white amorphous soHd having the characteristic odor of octyl alcohol. It is very slightly soluble in water, and very soluble in alcohol, polyethylene glycol 400, and com oil. It may be prepared directly from dioctyl sodium sulfo succinate dissolved in 2-propanol, by reaction with a methan olic solution of calcium chloride. 

Carbon—Sulfur Cleavage. The carbon—sulfur bond of DMSO is broken in a number of reactions. Attempts to form the DMSO anion by the reaction of DMSO with sodium result in cleavage accompanied by methane evolution (eqs. 10 and 11) (43) ... 

Strong bases such as methan olic potassium hydroxide, sodium methoxide, or 1,8-diazabicyclo [5.4.0] undec-7-ene (DBU), cause epimerization at the C-2 carbon or shift the beta-gamma double bond into conjugation with the lactone carbonyl (Fig. 4) (25,26). 

Propargyl alcohol (332) and (328) react readily with isocyanates in the presence of a basic catalyst to give 4-methylene-2-oxazolidinones (334) and 4-methylene-2-imidazolinones (336), respectively (63JOC991). In the absence of sodium methoxide the intermediate methanes (333) and ureas (335) were obtained and on treatment with sodium methoxide underwent ring closure. Moderate to excellent yields were obtained. 

Sodium and silver pyrazole salts (Section 4.04.2.1.3(vl)) are often used Instead of neutral pyrazoles to facilitate electrophilic attack on the ring nitrogen atoms. For example, pyrazolyl-methanes (234)-(236) have been prepared from pyrazole anions (Section 4.04.2.1.3(vlll)). Unstable 2-acetyllndazoles are obtained from the reactive silver salts of indazoles (Section 4.04.2.1.3 (x)). Electrophilic attack on the ring carbon atoms also occurs more readily in... 

An aiyl methane- or toluenesulfonate ester is stable to reduction with lithium aluminum hydride, to the acidic conditions used for nitration of an aromatic ring (HNO3/HOAC), and to the high temperatures (200-250°) of an Ullman reaction. Aiyl sulfonate esters, formed by reaction of a phenol with a sulfonyl chloride in pyridine or aqueous sodium hydroxide, are cleaved by warming in aqueous sodium hydroxide. ... 

ESCA has been used to determine the molecular structure of the fluoride lon-induced tnmenzation product of perfluorocyclobutene [74] and the products of the sodium borohydnde reduction of perfluoromdene [75] ESCA is also used to analyze and optimize gas-phase reactions, such as the bromination of trifluoro-methane to produce bromotrifluoromethane, a valuable fire suppression agent [76] The ionization energies for several hundred fluorme-containing compounds are summarized in a recent review [77]...
