Copper chloride, anhydrous

Dimethyl carbonate [616-38-6] and dimethyl oxalate [553-90-2] are both obtained from carbon monoxide, oxygen, and methanol at 363 K and 10 MPa (100 atm) or less. The choice of catalyst is critical cuprous chloride (66) gives the carbonate (eq. 20) a palladium chloride—copper chloride mixture (67,68) gives the oxalate, (eq. 21). Anhydrous conditions should be maintained by removing product water to minimize the formation of by-product carbon dioxide. [Pg.53]

Selenic Acid.—Selenic Acid, H2Se04, is also a il colourless syrupy liquid it can be produced by direct oxidation of selenium by chlorine water, but on concentra-I tion the resulting hydrochloric acid reduces the selenic acid I to selenious acid, as hydriodic acid reduces sulphuric acid. It is best prepared by addition of copper carbonate to the mixture of selenic and hydrochloric acids obtained in that way selenate and chloride of copper are formed the 1 mixture is evaporated to dryness, and the copper chloride is dissolved out with alcohol, leaving the insoluble selenate 1 behind. The selenate is dissolved in water, and on treatment with sulphuretted hydrogen, copper sulphide is precipitated, and removed by filtration the selenic acid is then concentrated if it contains a trace of water, it is a heavy liquid 5 but if quite anhydrous, it forms a solid, melting at 58°. [Pg.159]

Copper phthalocyanine can also be made by milling diiminoisoindolenine, copper(i) chloride, anhydrous sodium sulfate, and ethylene glycol at 100-110°C. [Pg.74]

Indolines 41, 42 are dehydrogenated by anhydrous copper chloride in pyridine to the corresponding indoles 41a, 42a [33, 35] with yields of up to 40%. The production of 5-(diethoxyphosphoryl)indoline (43) and 5-(dicthoxyphosphoryl[indole (43a) from 5-bromoindoline (5-bromoindole) and trialkyl phosphites by the Arbuzov reaction, catalyzed by nickel chloride has been described [35] ... [Pg.6]

Cuprous chloride supported on a Y-type zeolite by high-temperature anhydrous reaction gave a DMC productivity as good as the active carbon supported catalyst. Addition of tetraalkyl ammonium chlorides to copper chlorides on zeolites or alumina increased the DMC productivity and the catalyst life. In any case, active carbons are the most preferred supports for this reaction, compared to zeolites or alumina, because of higher DMC productivity when working with copper(II) chlorides. [Pg.722]

To 20 gm (0.092 mole) of p)nromellitic dianhydride, 8.0 gm (0.06 mole) of anhydrous copper chloride, and 108 gm (1.8 mole) of urea is added 0.1-0.4 gm ammonium molybdate catalyst. The reaction mixture is heated at 160°C for 30 min. The final product is washed with 6A HC1, dissolved in 200 ml cone H2SO4 and reprecipitated by dilution with water. The precipitate is washed with water (24 liter), filtered, and dried to give a product with MW approximately 1500 (dimer). The highest molecular weight obtained is 4,000 (6 repeat units)... [Pg.358]

Anhydrous copper chloride (0.121 g, 0.9 mmol) was dissolved in 10 mL boiling MeCN (distilled on CaH2), and a yellow solution was obtained. Then 0.3 mmol A-(azulen-l-ylmethylene)aniline was added, and the color of the solution turned to red. The solution was vigorously refluxed for 5 h, then MeCN was evaporated to mL. After cooling to room temperature, 50 mL benzene and 50 mL saturated NaHCOs solution were... [Pg.2094]

While the original Scholl conditions called for both a Lewis and protic acid, research by Kovacic and Kyriakis into the role of oxidizing agents (that facilitate the formation of radical cations) in the Scholl reaction led to the observation that benzene (12) when reacted in the presence of a heterogeneous mixture of anhydrous aluminum chloride and copper chloride afforded poly(para-phenylene) (13). It is important that Ihis reaction was conducted under mild conditions (25-35 °C) and was complete in only 2 h. As discoverers of one of the first Scholl reactions conducted under mild conditions, Kovacic and Kyriakis have greatly increased the synthetic utility of this reaction. [Pg.412]
