1881Jrnl. Chem. Soc. XL. 1181 The author has investigated the causes of explosions resulting from the products of the distillation of mineral naphtha when used for burning purposes. These products are known as ‘gasoline’, ‘benzoline’, ‘ligroin’, and ‘lubricating oil’. 1942H. Barron Mod. Synthetic Rubbers vii. 82 Straightforward rectification of petroleum yields: Petrol... Benzine... Ligroïn... Kerosene [etc.]. 1965Biol. Abstr. XLVI. 680/2 Experimental solvent extractions of wood rosin from pine stump chips were carried out in ligroin at 0, 20, 50, and 80°C. 1968B. J. Hazzard tr. Asinger's Paraffins iv. 402 Ligroin with a boiling range of 95–150°C (density = 0·745) containing 3·2 per cent of aromatics, 24·2 per cent of naphthenes, and 72·6 per cent of paraffins..can be 60–65 per cent nitrated in a single pass through the reactor. |
