Lime stabilization originated in Texas after World War II, and now it is used throughout the world. Lime is most commonly applied at a 4 wt % application or ca 11 kg/m (20 Ib/yd ) for 15 cm of compacted depth. It can be applied dry as hydrated time or granular quicklime or as a wet slurry. Distribution of the latter form is dusfless. Copious amounts (as much as 5—10%) of water are always needed in excess of the optimum moisture content of the soil. Then, a requisite for success is intimate mixing with a rotary mixer, followed by compaction to a minimum of 95% Proctor density.

Production and Economic Aspects. Aspirin is produced in the United States by The Dow Chemical Company, Rhc ne-Poulenc, and Norwich (a division of Proctor Gamble). Globally, Rhc ne-Poulenc has additional production faciHties in France and in Thailand. Bayer is self-suppHed from production units in Spain and Turkey over the years many small plants have been estabHshed around the world for regional or country supply. The aspirin market is increasingly globally suppHed. Aspirin is generally considered mature, and only population increases and new uses will affect its production and demand, which is thought to be of the order of 30—35,000 t for total world consumption. The May 1995 price was 8.30/kg (18). 

A commercially interesting low calorie fat has been produced from sucrose. Proctor Gamble has patented a mixture of penta- to octafatty acid ester derivatives of sucrose under the brand name Olestra. It was approved by the FDA in January 1996 for use as up to 100% replacement for the oil used in preparing savory snacks and biscuits. Olestra, a viscous, bland-tasting Hquid insoluble in water, has an appearance and color similar to refined edible vegetable oils. It is basically inert from a toxicity point of view as it is not metabolized or absorbed. It absorbs cholesterol (low density Hpoprotein) and removes certain fat-soluble vitamins (A, D, E, and K). Hence, Olestra has to be supplemented with these vitamins. No standard LD q tests have been performed on Olestra however, several chronic and subchronic studies were performed at levels of 15% in the diet, and no evidence of toxicity was found. No threshold limit value (TLV), expressed as a maximum exposure per m of air, has been estabhshed, but it is estimated to be similar to that of an inert hpid material at 5 mg/m. ...

The presence of alkaloids in Lobelia injlata, Linn., was first recorded by Proctor. Lobeline was prepared by Lewis as a basic oil from which Siebert made and analysed a series of salts and proposed the formula, CigHjsOjN. In 1921 Bohringer and Sohne protected a process for the isolation and separation of three alkaloids, a-, 3 and y-lobelines. In the same year Wieland published the first of a series of papers in which is described the isolation of several groups of alkaloids, to most of which constitutional formulae have been assigned and, in some cases, confirmed...
