Coloring matter Condensation

The attraction of coloring matter by charcoal is denominated mechanical, while the attraction of sulphuric acid by baryta is classed with chemical effects. But animal charcoal does not only attract coloring matter it aho decomposes metallic salts, and fixes their base by that same power of retention., Now it is known that chemical combinations and decompositions are produced by differences in intensity of one only chemical attractive force eollod affinity. It is evident that the same force is inherent in animal charcoal. This view is corroborated by the fact thot animal charcoal absorbs different compounds in different bnt determined quantities. Niepce has shown that iodine and chlorine gas ore condensed by the Inked portion of printed paper, while the white portion of the paper dees not retain any of the gases. Charcoal absorbs heat and light most readily.. It.Condenses... [Pg.1184]

It is normal to find potassium bitartrate crystals, associated with precipitated condensed coloring matter, in wine with several years aging potential. When phenols condense, they become bulky, precipitate and are no longer able to express their protective colloid effect. [Pg.28]

The above transformations result in a reduced anthocyanin content, contrasting with the increase in color. The new condensed pigments formed are more intensely colored than anthocyanins. Other anthocyanin and tannin breakdown reactions may lead to a loss of color, generally accompanied by a tendency towards yellow-orange hues. This is characteristic of the normal development of bottle-aged red wines. The breakdown of anthocyanins involves a loss of molecular structure in the red coloring matter, possibly accompanied by the appearance of a yellowish hue. [Pg.401]

At the end of this period the solution was removed from the condenser while still hot and titrated immediately with 0.002500 N sodium thiosulfate before any appreciable oxygen could be absorbed and oxidize iodide ion to triiodide ion. The disappearance of the yellow color of triiodide ion against a white background was used for the end point. These solutions usually had a slight brown tint at the end point, which was assumed to be organic matter distilled over from the soil. Accordingly, the blank was usually titrated first and its final color was used as a standard end point color for the other three solutions run with it. [Pg.204]

It is quite likely to find dense quark matter inside compact stars like neutron stars. However, when we study the quark matter in compact stars, we need to take into account not only the charge and color neutrality of compact stars and but also the mass of the strange quark, which is not negligible at the intermediate density. By the neutrality condition and the strange quark mass, the quarks with different quantum numbers in general have different chemical potentials and different Fermi momenta. When the difference in the chemical potential becomes too large the Cooper-pairs breaks or other exotic phases like kaon condensation or crystalline phase is more preferred to the BCS phase. [Pg.175]

The phase transition to color superconducting quark matter from the lower density regions at small temperatures (T < 5 a 10 MeV) is of first order, while the melting of the diquark condensate and the corresponding transition to normal quark matter at high temperatures is of second order. The presence... [Pg.349]

The wettability of sites where presumably antibody had been deposited on an antigenic film allowed rapid identification on proteins adsorbed on surfaces such as unoxidized metal or on others that were unfit for interference color or Coomassie Blue observation. Since all data confirmed those obtained by other means they will not be listed. Some details are of interest. Wherever water drops condensed and were allowed to evaporate, a dot of matter presumably transported by the moving air/water boundary was deposited in the center of each drop during evaporation. With reexposure to air saturated with water, condensation would start on each dot and result in a pattern identical to the first one. Coomassie Blue staining, or exposure to metal oxide suspensions 110), would show a reticulum of protein concentrated between the water drop sites. [Pg.280]

Contrary to expectations, small quantities of char were collected after each experiment. Soot formation was evident, and particularly prominent following the corn cob experiment. Coking of the volatile matter on the reactor wall beneath the window rendered the lower part of the reactor opaque. The water condensate was a light yellow color with a disagreeable (but not strong or particularly foul) odor. No tar was observed in the condenser, but the teflon tube connecting the reactor to the condenser was blackened. [Pg.241]

Liquid crystals occupy a unique position as a condensed material in physics, because they appear as various types of existing matter. Liquid crystals will also bring great progress in technology as they are used for high-vision color LCD and... [Pg.429]
