Liquids drying

Modem floor finishes contain mixtures of ingredients that when applied as a liquid dry to give a clear, durable film coating. Most floor finishes are combinations of polymers blended to provide unique and desirable characteristics such as durability, gloss retention, resistance to scuffing, fast-drying, and ease of removal. Polymers made up of more than one monomer or repeating unit are called copolymers.

Forms of Yeast. Yeast is available in several forms compressed yeast, cream (effectively a liquid), dried into pellets and powders claimed to be instantly active. Bakeries normally use compressed yeast, which with cream yeast must be kept under refrigeration. A supply of dried yeast will always be kept handy lest the yeast delivery should fail or the refrigerator breaks down.

The action of fuming nitric acid transforms benzene and its homologues (toluene, xylene) into nitro-compounds (nitrobenzene, etc.), which remain in the acid liquid, from which the mineral oil is subsequently separated. The liquid is then diluted with as much water and the solution neutralised with caustic soda solution and extracted with ether. The ethereal liquid (dried with a few granules of caldum chloride and filtered) is evaporated at a gentle heat and the residue weighed. If tar oils are present, this residue will consist of a reddish-brown oily liquid, heavier than water and with the odour characteristic of aromatic nitro-derivatives. The weight found, divided by 1-15 (mean sp. gr. of aromatic nitro-compounds), will give the volume. 

Enzyme micro-encapsulation is another alternative for sensor development, although in most cases preparation of the microcapsules may require extremely well-controlled conditions. Two procedures have usually been applied to microcapsule preparation, namely interfacial polymerization and liquid drying [80]. Polyamide, collodion (cellulose nitrate), ethylcellulose, cellulose acetate butyrate or silicone polymers have been employed for preparation of permanent micro capsules. One advantage of this method is the double specificity attributed to the presence of both the enzyme and the semipermeable membrane. It also allows the simultaneous immobilization of many enzymes in a single step, and the contact area between the substrate and the catalyst is large. However, the need for high protein concentration and the restriction to low molecular weight substrates are the important limitations to this approach.

Carbon tetrachloride (melting point -23°C, boiling point 76.7°C, density 1.5947, critical temperature 283.2°C, critical pressure 9714 psi - 67 MPa, solubility 0.08 g in 100 g water) is a heavy, colorless, nonflammable, noncombustible liquid. Dry carbon tetrachloride is noncorrosive to common metals except aluminum. When wet, carbon tetrachloride hydrolyzes and is corrosive to iron, copper, nickel, and alloys containing those elements.

Preparation of Slides—Most material may be dispersed easily in xylene or balsam. When these liquids dry the material remains firmly adherent to the glass slide. Dunn (1930) recommends the use of a stiff brush when mounting small particles with xylene or balsam. He claims the use of a brush in smearing the slide tends to produce a uniform distribution. Cover glasses may be used on the slide, but it must be remembered that under high magnification the use of a cover glass interferes...

While the curvature K doesn t exceed some value Kmax it is enough of the capillary ability of porous coating to transport of liquid, when curvature rises to K>Kmax the drainage of heated surface begins. On reaching the certain quantity of heat flux a heat exchange surface above liquid-level doesn t get sufficient amount of liquid, dry spots appear and then spreads to all over this part of surface. The liquid level is lower the maximum heat transfer coefficient is decreasing. 

Scahill, 1988). The products can be varied to yield up to about 56% liquids (dry) or 90% gases the char yields are about 10-15% in each case. Advanced pyrolysis processes are discussed in more detail in Section 111.

Although LA is too expensive to be the method of choice for solution analysis, the use of synthetic solutions and dual sample insertion systems for laser-induced aerosols mixed with liquids (dried and wet) has offset the lack of solid reference materials for quantitation [14,45 8,55]. A specific sample preparation procedure exists [118] for... 

Liquid drying involves dissolving soluble salts in water and adding this solution to a massive amount of another solvent in which the desired components are relatively insoluble. This technique is used to produce ferrite powders or pyrite solid solutions by dissolving the sulfates in water and adding this solution to 10 times their volume of acetone. The precipitate is filtered, dried, and heated in H2S to form the pyrites. ...
