The Reactions of Monomeric Styrenes.

“…3,4-Methylenedioxystyrene readily yields the dichloride when treated with chlorine in carbon tetrachloride solution (51 (72 per cent yield), 100,495,496). p-Methoxystyrene dichloride has been prepared in 25-30 per cent yield by treating anisóle with chloroacetal and hydrogen chloride at 60-70°C.…”

“…When styrene dichloride was heated for several hours at 0< _^>CHC1CH2C1 h2c0^\\ H20 in acetone (51,100,495)\\SOC12 (51) CaCOg in acetone (51)\\…”

With sodium acetate the yield was 70-80 per cent, with sodium carbonate 40 per cent, and with calcium hydroxide "good.…”

Oxidation of phenanthrene.

“…These investigators mentioned the oonoomitant produot1on of some diphen10 ao1d as the reaotion was oa.rried out. rater, phenanthraquinone wa.s prepared eleotro17tloally trom a suspension ot phenanthrene In twenty per oent sulfurio soid using oerium sulta te as a oatalyst by Meister, moius, and Bruning in 1902, (10 by Chowdbnry and Saboor (3) wh10h pure oxygen 1s subst1 tuted for air.…”

“…The aoid was diluted by adding water to the beaker in the ratio at (water to a01d) 10 At the end of' the heating period the phenanthrene was dumped into a oasserole oovered with 100 ml. distilled H2O, and titrated with .107 normal NaOH and phenolphthalein at 100 0 C. to determine acid oontent of the phenanthrene.…”
