Cochlea


Copper I) chloride, CuCl. White solid (CuClj plus HCJ plus excess copper or SO2). Gives carbonyl and phosphine complexes.  [c.111]

Absorbing each constituent preferentially by means of a reagent, e.g. CO2 in KOH solution, CO in acid or alkaline CuCl.  [c.186]

A propagation step involving growth around an active center follows RCH2—CHCl -h CH2=CHC1 —> RCH2—CHCl—CH2—CHCl and so on, leading to molecules of the structure  [c.21]

Other chlorinated naphthalenes. The other monochloronaphthalene (2-), the ten theoretically possible dichloronaphthalenes, and the fourteen trichloronaphthalenes have all been prepared, generally from the corresponding amino-derivatives by diazotization and treatment with CuCl. They are of little industrial importance.  [c.95]

Copper(II) chloride, CuClj. Dark brown (Cu plus excess CI2) forms green CuCl2,2H20 and many complexes, e.g. CUCI2, pyridine, generally containing bridging chlorines. Complex species, e.g. [Cu CU) ", (CuCl ) yellow or green, are also Known.  [c.111]

COT is prepared by the polymerization of ethyne at moderate temperature and pressure in the presence of nickel salts. The molecule is non-planar and behaves as a typical cyclic olefin, having no aromatic properties. It may be catalytically hydrogenated to cyclo-octene, but with Zn and dil. sulphuric acid gives 1,3,6-cyclooclairiene. It reacts with maleic anhydride to give an adduct, m.p. 166 C, derived from the isomeric structure bicyclo-4,2,0-octa-2,4,7-triene(I)  [c.122]

The diazonium salts usually decompose when warmed with water to give a phenol and nitrogen. When treated with CuCl, CuBr, KI, the diazo group is replaced by chlorine, bromine or iodine respectively (Sandmeyer reaction). A diazonium sulphate and hydroxyl-amine give an azoimide. The diazonium salt of anthranilic acid (2-aminobenzoic acid) decomposes to give benzyne.  [c.133]

Gattermann-Koch reaction Formylation of an aromatic hydrocarbon to yield the corresponding aldehyde by treatment with CO, HCl and AICI3 at atmospheric pressure CuCl is also required. The reaction resembles a Friedel-Crafts acylation since methanoyl chloride, HCOCl, is probably involved.  [c.187]

PoJy (3,3-bis (chloromethyl) oxelane), chlorinated polyether (R CHiCl) is widely used for injection moulding and coaling.  [c.292]

By oxidation with permanganate it forms pinonic acid, C,oH,<503, a monobasic acid derived from cyclobutane. With strong sulphuric acid it forms a mixture of limonene, dipentene, terpinolene, terpinene, camphene and p-cymene. Hydrogen chloride reacts with turpentine oil to give CioHijCl, bomyl chloride, artificial camphor .  [c.315]

Sandmeyer s reaction The replacement of a diazonium group by a halogen or pseudohalogen atom or group. It allows the conversion of an aromatic primary amine into the corresponding halogen compound. The amine is diazotized, and the diazonium salt solution is treated with CuCl, etc., causing the evolution of nitrogen and isolation of the halobenzene. Chloride, bromide and cyanide react easily potassium iodide is sufficient for preparation of the iodo-compound. Aromatic fluorides are prepared after isolation and thermal decomposition of the diazonium fluoroborate salt. See also Gattermann s reaction.  [c.351]
