Dichlorodiethyl ether

Solvent Treatment. Solvent processes can be divided into two main categories, solvent extraction and solvent dewaxing. The solvent used in the extraction processes include propane and cresyHc acid, 2,2 -dichlorodiethyl ether, phenol (qv), furfural, sulfur dioxide, benzene, and nitrobenzene. In the dewaxing process (28), the principal solvents are benzene, methyl ethyl ketone, methyl isobutyl ketone, propane, petroleum naphtha, ethylene dichloride, methylene chloride, sulfur dioxide, and iV-methylpyrroHdinone. 

Quite recently, Ciampolini and coworkers have reported the synthesis of two isomeric mked oxygen-phosphorus macrocycles and the crystal structures of their cobalt complexes. Synthesis of macrocycle 27 was accomplished by condensation of 1,2-bis-(phenylphosphino)ethane dianion with 2,2 -dichlorodiethyl ether in THE. The two isomers of 27 were isolated in 1.5% and 2% yield. The synthesis is formulated in Eq. (6.17), below.

Many unsaturated chloro- and bromo-hydrocarbons and many polychloro and polybromo compounds decompose by radical-chain mechanisms, but only the chloro compounds have been studied in reasonable detail, presumably owing to the complex nature of the chain reactions in the case of the bromo compounds. Other examples of compounds which undergo radical-chain decompositions are 2,2-dichlorodiethyl ether oxalyl chloride alkyl hypochlorites alkyl peroxychloroformates and alkyl chloro-sulphites in the gas phase ...

Iron(III) is extracted from hydrochloric acid media by diethyl ether, DIPE, 2,2 -dichlorodiethyl ether, and MIBK. For MIBK, the optimum concentration is 6-7 M HCl, while in the case of DIPE it is 7-8 M HC1. During the extraction of the iron(III) chloride complex, Ga, Tl(III), Au(III), Ge, As, Sb, and Mo are also extracted. Iron(III) can also be extracted from HCl medium with TBP, TOPO, or TO A in chloroform [1]. Iron(III) has been extracted from bromide media with TBP [2] and from citrate media with Aliquat 336S [3]. Crown ethers in CHCI3 have been also recommended for extraction of Fe(III) [4].
