Fluffy

Bromosuccinimide - easily purchased but I could only find one grade, ft s a very fluffy light orangy crystalline powder - use gloves and a mask, because bromine is VERY nasty. 

Black Pigments. The only black pigment used to an appreciable extent in inks is carbon black It is used in newsprinting, pubHcation, commercial and packaging printing therefore, in large quantities. Black pigments ate offered in fluffy or beaded forms and in a variety of particle sizes and physical properties. 

Texture. All limestones are crystalline, but there is tremendous variance in the size, uniformity, and arrangement of their crystal lattices. The crystals of the minerals calcite, magnesite, and dolomite are rhombohedral those of aragonite are orthorhombic. The crystals of chalk and of most quick and hydrated limes are so minute that these products appear amorphous, but high powered microscopy proves them to be cryptocrystalline. Hydrated lime is invariably a white, fluffy powder of micrometer and submicrometer particle size. Commercial quicklime is used in lump, pebble, ground, and pulverized forms. 

Although most lime is sold as quicklime, production of hydrated lime is also substantial. This product is made by the lime manufacturer in the form of a fluffy, dry, white powder, and its use obviates the necessity of slaking. Small lime consumers caimot economically justify the additional processing step that hydration entails. 

Another likely commercial starch is that from amaranth seed, an expanding crop for food use, particularly its flour. Amaranth starch granules (1—3 micrometers dia) have potential for numerous food appHcations, one of which is as a fat replacer because of their small size and especially after minor surface hydrolysis with a-amylase or glucoamylase to produce a fluffy surface (see Fat replacers). 

PMVEMA, supphed as a white, fluffy powder, is soluble in ketones, esters, pyridine, lactams, and aldehydes, and insoluble in aUphatic, aromatic, or halogenated hydrocarbons, as well as in ethyl ether and nitroparaffins. When the copolymer dissolves in water or alcohols, the anhydride group is cleaved, forming the polymers in free acid form or the half-esters of the corresponding alcohol, respectively. Table 7 illustrates the commercially available alternating copolymers and derivatives. 

Sodium and Potassium Benzoate. These salts are available in grades meeting the specifications of the 25ationalVormulary (18) and the Vood Chemicals Codex (19) (Table 7). Sodium benzoate [532-32-1] is produced by the neutralization of benzoic acid with caustic soda and/or soda ash. The resulting solution is then treated to remove trace impurities as weU as color bodies and then dried in steam heated double dmm dryers. The product removed from the dryers is light and fluffy and in order to reduce shipping and storage space the sodium benzoate is normally compacted. It is then milled and classified into various product forms, the names of which often bear Httle relationship to the actual form of the product.

Excess NaOH is used to start the reaction and not over 35% of the chromium is added as dichromate. At the end of the reaction, the thiosulfate is removed by filtration and recovered. The hydrous oxide slurry is then acidified to pH 3—4 and washed free of sodium salts. On calcination at 1200—1300°C, a fluffy pigment oxide is obtained, which may be densifted and strengthened by grinding. The shade can be varied by changes in the chromate dichromate ratio, and by additives.

The -toluenesulfonylhydrazide separates as fluffy, white platelets. The hydrazide, after cooling overnight in a refrigerator to complete crystallization, is filtered through a Buchner funnel. The filter cake is washed several times with petroleum ether (b.p. 35-60°), sucked dry, and then air-dried. / -Toluenesulfonyl-hydrazide (172-173 g., 90% yield) is obtained as a white, odorless, crystalline product, m.p. 101-104° (Note 7).

Spray-up Popular system with reinforced plastic production. An air spray gun includes a roller cutter that chops usually glass fiber rovings to a controlled short length before being blown in a random pattern (manually or automatically) onto a surface of the mold simultaneously the gun sprays catalyzed TS polyester plastic. The chopped fibers are plastic coated as they exit the gun s nozzle. The resulting, rather fluffy, RP mass is consolidated with serrated rollers to squeeze out air and reduce or eliminate voids. A closed mold...

This isoxazolium salt (10 g.) (obtained from the Aldrich Chemical Company, Inc.) was dissolved in 45 ml. of aqueous 1 M hydrochloric acid and reprecipitated by the slow addition with swirling of 400 ml. of acetone. The salt was collected, washed with 300 ml. of acetone, and dried overnight at 25° under reduced pressure (< 1 min.) to give a fluffy product, m.p. 206-208° (decomp.). An isomeric salt, A-ethyl-5-phenylisoxazolium-4 -sulfonate, which may be obtained by the usual synthetic procedure,2 is also useful in peptide synthesis. 

Ordinary rust typically is primarily non-ferromagnetic Fe203 (ferric oxide, or hematite). It is often red in color and can be found variously as a light and fluffy material or as a hard and dense tubercle or other type of deposit. 

Ferrous oxide (FeO) and hydrated iron oxide (FeOOH) can be found as a bright red to red-brown, light and fluffy deposits under various conditions, such as in cold FW tanks and freshly acid-washed or wet laid-up boilers. 

The aluminum hydroxide is formed as a fluffy, gelatinous network that entraps impurities as it settles, and this precipitate can be removed by filtration (Fig. 14.26).

Watermelon cell walls, prepared as follows, were kindly provided by Dr. Niels O. Maness of the Department of Horticulture and Landscape Architecture of Oklahoma State University. Ripe watermelon mesocarp tissues were placed on ice, diced into small pieces, and then homogenized on ice in Tris-saturated phenol to give enzymically inactive watermelon cell walls [6]. The solids were collected on two layers of mira cloth and washed with water until the smell of phenol was gone. The crude cell walls were further washed with chloroform methanol (1 1, W/V) and acetone until a fluffy consistency was obtained. The acetone-washed cell wall residue was dried in an oven at 60 °C and stored in a brown bottle.
