5a !?ALSlEIL-TlIE EFFEOT OF SALTS 0s DETEROESCE [Ysrclr, 1041 ketol group in respect to osnzone fornintion is very different in t,lie two compounds. Actioii of ll'tjs' so?iition.-After some defuiite nmount of absorption, the contents of the renction vessel were trnnsferred to a 500-C.C. glass-stoppered bottle, 50 C.C. of Wijs' solution20 adtled,, and tlie mixture wns lcft for hnlf nn hour in the dark. 30 C.C. of 10% potnssium iodide eolution nnd 200 C.C. of xnter were tlieti ndded, nnd the mixture wns t,itrntetl with 0.ls-tliiosulphnte. I n Tnble 11, oxygen equivalent to decrease in double linkings = dXerence in tliiosulphnte titre before nnd nfter absorption x 11,200/10,000. Annlyticnl rengerits.-With the esception of potassium dichromnte, nll the rengcnts employed were of ANALAB or A.R. qnnlity. Soiitbility .f ester.-The unosidised ester ivns soluble ( n t least to the estent of 0.5 C.C. in 3 c.c.) in rill the solvents n t room temperature. \Phikt the osidised ester was soluble in nll solvents n t 'i.?io, it cnnie out of solution in the nliphntic hydrocnrbons on cooling to room tempern t.ure.
