2- -6-hydroxy -chlorid

Commercially, aluminum chloride is available as the anhydrous AIQ, as the hexahydrate, AICI36 H2O, or as a 28% aqueous solution designated 32°Be. Polyalumiaum chloride, or poly(alumiaum hydroxy) chloride [1327-41 -9] is a member of the family of basic aluminum chlorides. These are partially neutralized hydrates having the formula Al2Clg (0H) 6 H2O where x = 1-5.

Tetravalent ruthenium chloride, RuC14. and the hydroxy chloride, RuiOH)CE, are intermediate products when RuCh is prepared by evaporating the tetroxide in TIG. When the hydroxychloride in hot IIQ is treated with Q2. it is converted to the tetrachloride. The anhydrous tetrachloride also is known. The tetrabromide and tetraiodide have not been isolated attempts to prepare these compounds result 111 the formation of the respective trihalides. 

Di-m-xylyl tellurium hydroxy chloride, [(CH3)2C6H3]2Te(OH)Cl. —The preceding compound reacts with a large bulk of water to form the hydroxychloride, consisting of small needles, M.pt. 239° to 240° C. An aqueous solution of the product has an acid reaction. When the needles are washed with water and dried in air they fall to a white powder, M.pt. 229° to 230° C., which also forms an acid solution in water. 

A solution of 1 part of a,a -diethyl-4,4 -dihydroxystilbene in 5 parts of pyridine is added drop by drop to the strongly cooled solution of 2 parts of phosphorus-hydroxy chloride in 5 parts of pyridine. The mixture soon solidifies to a crystalline magma. It is allowed to stand in ice for A hour and then for an hour at room temperature. The mass is then poured into an excess of saturated sodium bicarbonate solution. Unconsumed parent material is removed by extraction with ether. The aqueous solution is then mixed with 2 N hydrochloric acid, whereupon the primary phosphoric acid ester of a,a -diethyl-4,4 -dihydroxystilbene of the formula is precipitated in the form of a voluminous white powder. By recrystallization or reprecipitation this ester may be further purified. 

The thermal treatment is one of the factors which controls the properties of the final catalyst [56]. The total surface area (in the range between 100 and 300m2g l) decreases with increasing reduction temperature however, the nickel surface area (typically 20-50 m2g l) increases which is probably due to a higher degree of reduction. The best precursor with respect to a high surface area is the hydroxycarbonate. The surface areas of catalysts prepared from hydroxy-chlorides and nitrates are smaller by about a factor of two. Nickel particle sizes are in the order of 5nm for such catalysts. 

Corrosion products such as the oxides, hydroxides, carbonates, sulfates, basic sulfates hydroxy carbonates, hydroxy chlorides are formed in the various environments (marine, urban, rural, industrial) and the initially loosely bound products may become adherent in the course of time. Corrosion can occur in the pores of the corrosion product layers. The low corrosion rate observed in atmospheric corrosion, R has been expressed as ... 

In the hydroxy chloride Zn5(0H)8Cl2-H20, the structure is based on charged layers with chloride ions and water molecnles in between. One-quarter of the zinc ions are missing from a Zn(OH)2 layer, and for each absent Zn + two snch ions are added beyond the snrfaces of the layer so that the composition is Zn5(OH)8 +. The charge is balanced by the chloride ions between the layers. The Zn + ions are tetrahedrally coordinated on the onter snrfaces of the...

Tribenzylarsine hydroxyhalides.—Tribenzylarsine hydroxy-chloride, (CeH5.CH2)8As(OH)Cl, results as a by-product in the preparation of tribenzylarsine (p. 77). It is also formed when hydrochloric acid is added to an aqueous solution of tribenzylarsine oxide it is a colourless, crystalline compound, M.pt. 162° to 163° C. The hydroxy-bromide crystallises in tablets, M.pt. 128° to 129° C., and the hydroxy-iodide is a body of rather indefinite composition, containing one molecule of water and melting at 78° C. The latter substance is obtained by the action of alcohol on tribenzylarsine di-iodide, which turns red and melts at 95° C. 

Arsenic trichloride (butter of arsenic) [7784-34-1] M 181.3, m 31.2", b 25"/llmm, 130.0"/atm, d 4 2.2. Reflux the trichloride with arsenic for 4hours, then fractionally distil it. The middle fraction is stored with sodium wire for two days, then again distilled [Lewis Sowerby / Chem Soc 336 1957]. It fumes in moist air forming the solid hydroxy-chloride [AsCl(OH)2] and is readily hydrolysed by H2O to form arsenious acid. POISONOUS. [Schenk in Handbook of Preparative Inorganic Chemistry (Ed.

Triphenylbismuthine hydroxy chloride, (CeH5)3Bi(OH)Cl. — When the corresponding dichloride is dissolved in chloroform containing a little light petroleum and moist ammoma is passed in, a white solid is deposited. This is collected and washed first with cold water and then with hot water to remove the ammonium chloride formed. The hot water produces effervescence and evolution of chloroform, which is apparently present as chloroform of crystallisation. The pure compound is a white powder, M.pt. 160° to 161° C., completely soluble in cold chloroform, hot alcohol or nitrobenzene, moderately soluble in benzene, xylene, acetone or ether, and insoluble in water or light petroleum. When treated with methyl magnesium iodide only triphenylbismuthine and its dichloride are obtained.
