(1) Because the salts of these ions and the alkane sulfonates and alkyl hydrogen sulfates are largely water soluble, the detergent remains dispersed in the water.(2) This method of production is still used although oxidation of methane, pyrolysis of alkanes , and cracking of hydrocarbons are more commonly encountered.(3) Furthermore, there was no evidence of ethyl esters, dimers, alkanes or alkenes, which might be expected for an oxidative reaction.(4) In some yeast species, peroxisomes may be induced by growth on methanol, alkanes , fatty acids, and cadmium.(5) Paraffin waxes are mixtures of high molecular weight alkanes , and therefore are not esters.
