Chloroformic acid

The reaction of phosgene (carbonic dichloride [75-44-5]) with alcohols gives two classes of compounds, carbonic esters and carbonochloridic esters, commonly referred to as carbonates and chloroformates. The carbonic acid esters (carbonates), R0C(0)0R, are the diesters of carbonic acid [463-79-6]. The carbonochloridic esters, also referred to as chloroformates or chlorocarbonates, C1C(0)0R, are esters of hypothetical chloroformic acid [463-73-0] CICOOH. [Pg.37]

In eadier Hterature carbonochloridic esters are referred to as chloroformates or chlorocarbonates because of the stmctural parallel with formic acid [64-18-6]., chloroformic acid, and carbonic acid. Before 1972, chloroformates were indexed in Chemicaly4bstracts, Eighth Collective Index, under formic acid, chloroesters whereas, in the Ninth Collective Index (Dec. 1990), they are referred to as carbonochloridic acid esters. Table 1 fists the common names of carbonochloridates or chloroformates, the CAS Registry Numbers, and the formulas. [Pg.37]

The esters of carbamic acid, the urethanes, which are formed by combination of alcohols with compounds of the cyanic acid series, are stable substances. The reaction by which they are formed is, likewise, capable of undergoing many variations. It may be recalled that a second method of synthesising them consists in acting on the esters of chloroformic acid with ammonia and amines. [Pg.134]
