Making, 33 solubility

The glyptals made from phthalic anhydride and glycerol were developed as compositions for use in paints and varnishes. If the reaction was carried out too long the product became intractible. But under milder conditions, other products could be obtained which could be used in making soluble products and then they could be set further after forming. It was learned that by modifying the reaction mixture with some monobasic acid to balance the hydroxyls and carboxyls in the reaction mixture, more soluble products could be obtained. Kienle of General Electric, was one of the early developers of these products. Later many other alkyd resins from other polyhydroxyl compounds and poly acids were produced for technical use. [Pg.55]

Plates, sheets, rods, tubes, wires and gauzes may be used for electrodes. Plates are the most widely used. Metal cathodes and insoluble metal anodes are generally made of rather thin sheets thicker plates are only used for making soluble metal anodes and electrodes of nonmetallic material. Rod-shaped elee-trodes are hardlyfcever used. They are only used in cases where plates would... [Pg.179]

Make solubility tests on the test compounds shown to the left in each of the solvents listed. Note the degree of solubility in the solvents, cold and hot, and suggest suitable solvents, solvent-pairs, or other expedients for crystallization of each substance. Record the crystal form, at least to the extent of distinguishing between needles (pointed crystals), plates (flat and thin), and prisms. How do your observations conform to the generalization that like dissolves like ... [Pg.38]

The reaction of tris(trimethylsilyl)silyllithium with AICI3 at -78°C yields the aluminate [Li(THF)4][AlCl3Si(SiMe3)3] [10], This Lewis base adduct can be interpreted as an LiCl-containing intermediate of the reaction towards [(MesSOsSiAlCL]. As a building block this intermediate makes soluble alumosilicates feasible that can be used in homogeneous catalysis. [Pg.163]

Within the industrial applications of HP, besides the antimicrobial actions they present, they have been used in some countries for soy protein hydrolysis, for freezing, to soften meat, for discoloration of hemoglobin, as by-products in the meat industry, to deodorize proteins, and to make soluble or modify fish proteins (Cheftel, 1995 Palou et al., 2002 Ting and Marshall, 2002a,b). Some examples of the interaction of HP with biological structures of foods are presented in the next section with a major description on milk and its products. [Pg.220]

When this theory was used to predict the solubility of polymers in a variety of solvents, it was only partially successful. It was apparent that other intermolecular forces were at work which could not be calculated by this simple procedure. Hydrogen bonding, probably the strongest type of intermolecular force in a nonelectrolyte, was the clue for making solubility parameter theory work. [Pg.10]

As mentioned above, the mineral in bones and teeth contains COs ions so its solubility properties will not be the same as depicted for HAP in Figure 1. In fact, the presence of COs ions increases the solubility product and the rate of dissolution in acids significantly. Taking dental enamel because it is better crystallized than bone mineral, an activity product of 5.5 x 10 mol F (presumably at 25°C) has been reported (Patel and Brown 1975). This compares with 3.04 x 10 mol 1 at 25°C for stoichiometric HAP (McDowell et al. 1977). Both activity products are based on (Ca ) (P04 ) (OH ) where the parentheses indicate activities. In more recent studies, the activity of the C03 ion has been included in the calculation of activity product of enamel (Aoba and Moreno 1992). This necessitated making solubility measurements under controlled CO2 partial pressures. [Pg.428]

Elie Seignette (La Rochelle 1632-1698) in making soluble tartar (potassium tartrate) from tartar (potassium hydrogen tartrate) substituted soda (sodium carbonate) for potash (potassium carbonate) and obtained a new salt, potassium sodium tartrate, now called Rochelle salt or (on the Continent) Seig-nette s salt. This he called sel polychreste and after its discovery in 1648-1660 (probably 1655) brother Jehan (Rochelle 1623-1663), who kept the... [Pg.36]

Aabs 400-420 nm (dependent on synthesis) band g of 2.5 eV. The yellow/green fluorescence of PPV has a structured emission band with >Ui 520 and 551 nm [103]. PPV has very low solubility in common CMTganic solvents, and thus there has been a great deal of research on making soluble PPV derivatives (such as MEH-PPV and MPS-PPV, see below), see Ref. [104]. [Pg.188]
