Ethylenic linkages, determination number

The number of ethylenic linkages In a given compound can be established with accuracy by quantitative titration with perbenzoic acid. A solution of the substance ajid excess of perbenzoic acid in chloroform is allowed to stand for several hours at a low temperature and the amount of unreacted perbenzoic acid in solution is determined a blank experiment is run simultaneously. [Pg.809]

The determination of the content of oxyethylene groups in ethylene oxide - propylene oxide can also easily be carried out by nuclear magnetic resonance spectrometry [93, 100] withont chemical splitting of the ether linkage. However, it is difficult to identify the base componnds by this method. A number of methods for the cleavage of ethers have been stndied bnt few were applied to the identification of the base compounds of the polyurethane polyethers. [Pg.165]
