Reduction of WCl 6 can be effected with a mixture of tetrachloroethylene and tetraphenylarsonium chloride: [5] 2 WCl 6 + Cl 2 C=CCl 2 + 2 (C 6 H 5) 4 AsCl → 2 (C 6 H 5) 4 As[WCl 6] + Cl 3 C−CCl 3. The W(V) hexachloride is a derivative of tungsten(V) chloride. It reacts with arsenic or hydrogen arsenide to form tungsten arsenide. [6] [7]

Less than 5% fines Cu ≥ 6 and 1 ≤ Cc ≤ 3 SW Well-graded sand Cu < 6 and/or Cc < 1 or Cc > 3 SP Poorly graded sand Sands with Fines. More than 12% fines Fines classify as ML or MH SM Silty sand Fines classify as CL or CH SC ...
The material dissolves in concentrated hydrochloric acid, forming (H 3 O) 2 [W 6 Cl 14](H 2 O) x. Heating this salt gives yellow-brown W 6 Cl 12. [1] The structural chemistry resembles that observed for molybdenum(II) chloride. Tungsten(II) chloride is prepared by reduction of the hexachloride. Bismuth is a typical reductant: 6 WCl 6 + 8 Bi → ...
This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately.
With chloride salts, TiCl 4 reacts to form sequentially [Ti 2 Cl 9] −, [Ti 2 Cl 10] 2− (see figure above), and [TiCl 6] 2−. [21] The reaction of chloride ions with TiCl 4 depends on the counterion. [N(CH 2 CH 2 CH 2 CH 3) 4]Cl and TiCl 4 gives the pentacoordinate complex [N(CH 2 CH 2 CH 2 CH 3) 4][TiCl 5], whereas smaller [N(CH 2 CH 3) 4 ...
H 2 C=CH 2 + HCl → CH 3 CH 2 Cl. In oxychlorination, hydrogen chloride instead of the more expensive chlorine is used for the same purpose: CH 2 =CH 2 + 2 HCl + 1 ⁄ 2 O 2 → ClCH 2 CH 2 Cl + H 2 O. Secondary and tertiary alcohols react with hydrogen chloride to give the corresponding chlorides.

The reaction of the CFCs which is responsible for the depletion of ozone, is the photo-induced scission of a C-Cl bond: [10] CCl 3 F → CCl 2 F. + Cl. The chlorine atom, written often as Cl., behaves very differently from the chlorine molecule (Cl 2). The radical Cl. is long-lived in the upper atmosphere, where it catalyzes the conversion of ...
