Tri-chloride

We see, therefore, that magnesium normally forms a dichloride and not a mono- or tri-chloride. Similar calculations can be made for many systems, but greater uncertainties arise, especially when...

FlC. 9. Nonparallel regeneration of the functions for bilirubin binding and fatty acid binding in bovine plasma albumin. The oxidative regeneration of reduced albumin was carried out at protein concentrations of 1 ft,M at 25°C in 0.10 M Tris-chloride buffer, pH 8.0, containing 1 mM EDTA and 1 mM reduced and 0.10 mM oxidized glutathione (Johanson et al, 1977, 1981). 

Therefore, with the catalyst under consideration, ground a-titanium tri-chloride-AlCl(CjH6)2, the totality of active centers is involved in the catalytic process, once the polymerization starts. We may deduce from the time constancy of the polymerization rate from the very beginning of the reaction that, in this case, the number of active centers is invariable and that the calculated value corresponds to the number of conventional active centers involved in the polymerization, in steady-state conditions. 

A. Werner says that the hepta- and enna-halides can be explained on the assumption that the co-ordination positions are occupied by iodine molecules. The nonexistence of the tri-chlorides, says A. Werner, is to be attributed to chlorine being unable to act as a central atom. ... 

Resuspend the cell pellets in ice-cold 0.1 M Tris chloride buffer, pH 9.2, using 4 ml of buffer per gram of cells. Transfer the resuspended cells to a small metal sonication container and pack in an ice-water bath. (The cells may be stored frozen at —20 or —70°C at this point for later use, if desired.)... 

M Tris chloride, pH 8.8—Dissolve 91 g of Tris (tris-hydroxytnethyl-aminomethane) free base in about 375 ml of distilled water. Titrate the solution to pH 8.8 with concentrated HC1 and dilute to 500 ml with distilled water. 

Protein molecular weight standards—Suggested standards are phosphorylase (97,400 Da), bovine serum albumin (66,200 Da), ovalbumin (45,000 Da), carbonic anhydrase (31,000 Da), soybean trypsin inhibitor (21,500 Da) and lysozyme (14,400 Da) at 1 mg/ml each in a single mixture in 0.01 M Tris chloride buffer, pH 7.0 (prepared by dilution of the stock 1 M buffer above). Approximately 2 ml of this solution will be required. 

Unknown protein solutions (approximately 1 mg/ml in 0.01 M Tris chloride buffer, pH 7.0)—It is convenient to prepare the unknowns in larger volumes (100 to 500 pi) and to dispense them to students as 20-pl samples in microcentrifuge tubes. Any of the proteins used as standards or other readily available proteins with molecular weights within the range of the standards may be used. 

M Tris chloride buffer, pH 9.2—Dissolve 6.05 g Tris free base in distilled water, titrate to pH 9.2 with... 

Reaction of Alcohol and Phosphorus Tri-chloride.—Three other reactions also prove that in alcohol we have the oxygen and hydrogen in the same grouping as in water, as (—O—H). Two of these... 

The chlorine of the phosphorus tri-chloride takes the place of the hydroxyl group of water, or, in other words, the phosphorus removes the hydroxyl and unites with it forming an hydroxyl compound, i.e., P(0H)3 or H3PO3, phosphorous acid. When phosphorus tri-chloride reacts with alcohol the products of the reaction are found to be ethyl chloride and phosphorous acid, and we may write the reaction ... 

The two reactions then of phosphorus tri-chloride with water and with alcohol are exactly analogous. Phosphorous acid is formed in both cases due to the union of phosphorus with the (OH) group. In the case of water a compound of hydrogen and chlorine is the other product,... 

Therefore, the amount of iodine, in grams, absorbed by 100 grams of the acid, is, for these three acids, respectively, 90.07, 181.42, 274.1. These numbers are known as the iodine values, also as, the Hubl, or Wijs numbers, from the names of men who devised the two most accurate methods of determination. In practice, iodine is used more often than bromine. The form in which the iodine is used is that of iodine mono-chloride, ICl, or iodine tri-chloride, ICI3. The first is made by mixing a solution of iodine and mercuric chloride,... 

The iodine tri-chloride solution is made by the addition of chlorine to an iodine solution,... 

Because, as we shall see later, the mono-chlor-methyl benzene yields benzyl alcohol it is known as benzyl chloride. The di-chlor-methyl benzene similarly yields benzaldehyde, and is, therefore, called benzal chloride, and the third is also called benzo tri-chloride.
