2-chloroethyl acetal

Acetyl chloride 2-Chloro-1 -methylethyl acetate, 2-chloropropyl acetate 2-Chloroethyl acetate For EO content <30%, the ratio of chloroethyl acetate to total chloroethyl and chloropropyl acetates may be used to obtain percent of EO. A calibration is required for values of EO >30% [16].

All attempts to isolate 2-halogeno-l,3-dioxolanes or -1,3-dioxanes were unsuccessful. For instance, 2-chloro-l,3-dioxolane was detected only by photochlorination of 1,3-dioxolane (Ref. 118) at low temperature and 2-chloro-2-methyl-l,3-dioxolane was prepared by treatment of 2-methyl-l,3-dioxolane-2-carboxylic acid with phosphorus pentachloride at —60°, and shown119 to rearrange to 2-chloroethyl acetate on warming to 0°. For other examples of such problems, see especially, references 120 and 121. 

CH3OC R is a methoxycarbonyl derivative whereas CH3CO R is the acetoxy derivative. In naming esters containing one or more substituents, it is necessary to indicate specifically in which portion of the molecule the substituents occur, eg, ClCH2COOCH2CH3 is ethyl chloroacetate [105-39-5] and CH3COOCH2CH2Cl is 2-chloroethyl acetate [542-58-5]. 

The Carbide and Carbon Co began large scale manuf of EtnO thru ethylene chloro-hydrin in 1925 and by the direct oxidation of ethylene in 1937. Dow entered the field in 1939 1941 Jefferson and Wyandotte in 1941 and Mathieson Chem Corp in 1951. These four Co s used the chlorohydrin method. US consumption, which was in 1939 108 million pounds, increased in 1949 to 354 million Several laboratory methods of prepn are described in Ref 17, pp 75—7. In one of them hydroxide is added gradually to a soln of 2-chloroethyl acetate heated to a temp betwn 40 150°C. An excess of unreacted base is avoided. The reaction proceeds as follows H C1 CH2... 

In the first class, the base sensitivity of groups in the p-elimination orthogonal set (section 1.2.6) can be circumvented by incorporating the C—H activating group in latent form as shown in Scheme 1 27,44 Cleavage and reduction of a tetrahydropyranyl acetal in the presence of a sensitive dimethyl acetal was accomplished by conversion of the 2-chloroethyl acetal 27.1 to a 2-(phen-...

When media other than water are used, different but related processes operate. Thus, the oxidation of ethylene in acetic acid can be directed to give vinyl acetate, ethylene glycol acetate, or 2-chloroethyl acetate [9]. Similarly, the synthesis of acetals or ketals can be achieved in an alcoholic medium [10]. Although the oxidation of alkenes in such a medium is closely parallel to the Wacker process, the chemistry of these reactions is far beyond the scope of this section, which is limited to Wacker-type reactions in aqueous media, and will not be discussed here.

As discussed in Chapter 8, ferric chloride-catalyzed reaction of alkoxylates with acetyl chloride results in decomposition of the polyether structure, converting ethylene oxide units to mainly 2-chloroethyl acetate. The reaction mixture develops a red color which is proportional to the amount of polyether originally present. It has not been determined exactly which reaction product produces the colored complex with ferric ion, but the phenomenon has been demonstrated as suitable for quantitatively determining low levels of polyether (108). Since the procedure cannot be used with aqueous samples, its application is limited.
