| titleOfInvention | Process for the preparation of benzoin compounds |
| abstract | (Nuclear substd.) benzoquinone prepn. Title cpd. is prepd. by reactg. at 0 to 100 degrees C, pref. 10 to 40 degrees C a mixt. of 1 mole aniline or o- or m-substd. aniline, 0.65 to 0.9, pref. 0.7 to 0.8 mole chromic acid and H2SO4(3N to 10N) for a length of time such that y2 = 12500/(x1/2 + 0.8) (where x is time (in mins) and y is temp. in 0 degrees C. x is not >360 degrees C). Thhe sulphuric acid contains 0.1 to 7% wt. aniline or its derivs. Higher yields of benzoquinone are easily obtd. by this process which is used to produce other chemicals e.g. naphthaquinone. |
