Hydroxy-2-methylpropiophenone (30 g., 0.183 mole) was added slowly to 150 ml. of concentrated sulfuric acid with stirring. The temperature rose and the solution turned dark brown. The temperature remained at 80° for 10 minutes and then slowly fell. After 1 hour the dark solution was poured onto 200 g. of cracked ice. The mixture was extracted with two 100-ml. portions of ether. The ethereal solution was washed with two 100-ml. portions of water, two 100-ml. portions of saturated aqueous sodium bicarbonate, and again with two 100-ml. portions of water. It was dried over anhydrous potassium carbonate, and the solvent was removed. The residue was distilled to give 18-19 g. (67-71%) of a pale yellow liquid, b.p. 65-66° (0.6 mm.) [lit2, b.p. 120° (15 mm.)], nzod 1.5510 (lit.2 n23d 1.5511) infrared band (neat) at 5.80 n (C=0). 

A. Stock found that the m.p. of phosphorus depends on the rate of heating and in contradistinction to A. Smits and H. L. de Leeuw, A. Stock and E. Stamm did not find the m.p. of yellow phosphorus to be altered by heating it to 100° followed by rapid cooling. Molten phosphorus is easily obtained as an under-cooled liquid, even at temp. 40° below its m.p. A. Bellani, and H. Rose noted that contact with solid phosphorus causes an immediate solidification of the under-cooled liquid. The phenomenon is particularly marked with phosphorus which has been boiled under an aq. or alcoholic soln. of potassium hydroxide. Observations on this subject were made by T. de Grotthus, J. B. Kallhofert, A. Schrotter, F. P. Venable and A. W. Belden, P. Heinrich, J. W. Retgers, and D. Gernez. The last-named also measured the velocity of crystallization of the under-cooled liquid—vide supra.
