20. A water blended fuel composition made by combining: a normally liquid hydrocarbon fuel; water; an acid having a pKa of about 1.5 up to about 6; a polyisobutene-substituted succinic acid wherein the polyisobutene group has a number average molecular weight in the range of about 750 to ...
BIf both assertion and reason are true but reason is not correct explanation of assertion. CIf assertion is true but reason is false. DIf both assertion and reason are false.Submit The molecular formula of an organic compound is C6H12O6 and the empirical formula is CH2O the value of n is ...
[38], 1H NMR spectroscopy at 300 MHz (Solvent CDCl3) (Fig. 4) showed different peaks: (a) the methylene groups (CH2–) at 2.6 ppm and (b) the methylene (CH2O–) at 3.7 ppm. In the 1HNMR spectra of copolymer (PANI–PEO2000), a wide signal in the ...
The proteins were isotope-labeled: Endoprotease-treated samples were incubated with 100 mm 13CD2O (heavy formaldehyde) in the presence of 50 mm sodium cyanoborohydride and control samples were incubated with 12CH2O (light formaldehyde) under the same conditions. Heavy and light labeled proteins were...
Example 2.-Under conditions described in Example 1, 602 parts of di(p-chloroethyl) formal, 258 parts of 1,3-dioxolane and 4 parts of sulfuric acid gave 105 parts of di(p-chloroethyoxymethoxy) ethane (ClC3CaHaOCH2OCH2CHsOCH2OCHaCHaCl) B. P. 1280 C./28 mm. Unconverted reactants and...
, H2O, and CH2O MF extensions (Kujawinski and Behn, 2006). To do the formula extensions, the KMD and z* values for each of these bases are calculated and then used to assign MF through the addition or subtraction of the series bases....
