The latter process provides a high-yield route to 1,1-binaphthol: [22] Such compounds are intermediates in the synthesis of BINAP and its derivatives. [20] Copper(II) chloride dihydrate promotes the hydrolysis of acetonides, i.e., for deprotection to regenerate diols [23] or aminoalcohols, as in this example (where TBDPS = tert ...
Copper(I) chloride is produced industrially by the direct combination of copper metal and chlorine at 450–900 °C: [11] [12] 2 Cu + Cl 2 → 2 CuCl Copper(I) chloride can also be prepared by reducing copper(II) chloride with sulfur dioxide , or with ascorbic acid ( vitamin C ) that acts as a reducing sugar : [ 13 ] [ 14 ]
C 12 H 14 O 4: dillapiole: C 12 H 15 NO: 1-benzyl-4-piperidone: 3612-20-2 C 12 H 16 N 2: N,N-Dimethyltryptamine: 61-50-7 C 12 H 16 O 3: asarone: C 12 H 16 O 3: elemicin: C 12 H 16 O 3: isoelemicin: C 12 H 16 O 3: oudenone: C 12 H 16 O 4: 2,4,5-Trimethoxypropiophenone: C 12 H 16 O 7: arbutin: 497-76-7 C 12 H 17 N 5 O 4 S thiamine nitrate: C 12 H ...
The LD50 (oral, rats) is 756 mg/kg. Animal studies have shown that 1,2,4-trichlorobenzene affects the liver and kidney, and is possibly a teratogen. [4] There is no regulated occupational exposure limit for chemical exposure, but the National Institute for Occupational Safety and Health recommends no greater exposure than 5 ppm, over an 8-hour workday.
Bromochlorodifluoromethane (BCF), also referred to by the code numbers Halon 1211 and Freon 12B1, is a haloalkane with the chemical formula C F 2 Cl Br.It is used for fire suppression, especially for expensive equipment or items that could be damaged by the residue from other types of extinguishers. [1]
Ammonium persulfate is prepared by electrolysis of a cold concentrated solution of either ammonium sulfate or ammonium bisulfate in sulfuric acid at a high current density. [2] [3] The method was first described by Hugh Marshall.
Copper(II) acetate, also referred to as cupric acetate, is the chemical compound with the formula Cu(OAc) 2 where AcO − is acetate (CH 3 CO − 2).The hydrated derivative, Cu 2 (OAc) 4 (H 2 O) 2, which contains one molecule of water for each copper atom, is available commercially.
12 NaCuCl 2 + 3 O 2 + 2 H 2 O → 4 Cu 2 (OH) 3 Cl + 4 CuCl 2 + 12 NaCl. The product from this process is of fine particle with size of 1 ~ 5 μm and is usable as an agricultural fungicide. [6] Astable, free-flowing, non-dusty green powder with typical particle size of 30 ~ 100 microns has been used in preparation of uniform animal feed ...
