We have prepared from the non‐saponifiable matter of wheat germ oil thress aflophanates: 1. M.p. 250°. This is a possibly the allophante of β‐amyrin. The alcohol regenrated from the allopohante has no vitamin E potency. 2. M.p. 138°, readily crystallizing in long needles. The analysis agree with values required by monollophantes of an alcohol, C39H50O2. The alcohol from this allophante apparenelly has some vitamin E potency, but less than that from the third allophanate. 3. M.p. 158‐160°. From this allophanate, the alcohol—for which we propose the name α‐tocopherol—when given in a single dose of 3 mg. always enables vitamin E‐deficient rats to bear young. α‐Tocopherol shows a characteristic absoption band at 2980 Å., E1 per cent1 cm. = 90 ca. Treatment with methyl alcoholic silver nitrate converts it to a substance which has absorption bands at 2710 and 2620 Å respectively, E1 per centcm. = 480 ca., and possesses and some vitamin E activity. α‐Tocopherol yields a crystaline p‐nitrophenylurethane melting at 120‐131°. Analyses of both the urethane and the allophanate indicate a provisional formula for α‐tocopherol of C29H50O2

o-Xylenol is not available in quantity and is difficult to prepare. The preparation of oxyloquinone and hydroquinone from it by the generally useful method previously described3 is, therefore, impracticable. The present paper reports improvements in the previously de-scribed4'5•6 synthesis of this quinone from oxylene via the o-nitro compound and the amine. The yields obtained in the three steps are, respectively, 85, 75 and 33%, or an over-all yield of 21% of quinone from hydrocarbon. The corresponding over-all yield previously reported by this method is 12%.4-5,6 Procedure 3-Nitro-o-xylene.-o-Xylene (50 g.) is nitrated at -10 to 0 0 by stirring it vigorously and dropping into it slowly a mixture of sulfuric acid (100 g.) and nitric acid (50 g., d.1.4). During the addition, the tip of the dropping funnel is shielded from spray by keeping it well up in the neck of the flask, out of the path of the droplets thrown by the stirrer. This prevents any contact of xylene with an excess
