The kinetics of alcoholysis of trichloroacetyl chloride with butanol in carbon tetrachloride were studied by dielcometry and IR spectroscopy. The reaction is reversible, and it involves intermediate formation of 1-butoxy-1,2,2,2-tetrachloroethanol and 1,1,2,2,2-pentachloroethanol.

, p. 1195 - 1200 (2013)
Organic halogen derivatives, viz., hexachloroethane, 2,2,2- trichloroethanol, 2,2,2-tribromoethanol, butyl trichloroacetate, 2,2,2-trichloroethyl methacrylate, can efficiently activate fluorescence of lactone forms of rhodamine dyes by UV irradiation through the UFS-1 light filter in both solutions and polymer poly(methyl methacrylate) films. This ability is also typical of the copolymer of methyl methacrylate and 2,2,2-trichloroethyl methacrylate, which is promising for the development of detecting media for archive optical data storage with fluorescent readout.

By study the reaction between trichloroacetyl chloride and butanol in CCl4 at 20 deg C we have shown that dielectrometry can be used to monitor the kinetics of chemical reactions involving the formation of unstable intermediates.The kinetic curves describing the changes in capacity of the system go through a maximum.A method of calculating the rate constants of the reactions and the molar permittivity of the intermediate, as well as the time of its maximum concentration, is proposed.

Semenyuk, G. V.,Oleinik, N. M.,Razumova, N. G.,Zhil'tsov, N. P.
, p. 1225 - 1231 (2007/10/02)
The kinetics of the reactions of butyryl chloride with 1-butanol in toluene, catalyzed by trimethylacetic, acetic, and monochloro- and trichloroacetic acids, were studied.It was shown that these acids hardly differ at all in catalytic activity, and the Taft constant was ρ* 0.The obtained data are compared with those for the alcoholysis of 3,5-dinitrobenzoyl chloride and trichloroacetyl chloride and also for certain aminolysis reactions.Details of the mechanism of bifunctional catalysis are amplified.

, p. 49 - 62 (2007/10/02)
IR spectra of ten n-alkyl trichloroacetates CCl3COO(CH2)nCH3 (R'-TCA) in the crystalline state (R'-TCAs with n=4, 5 in the glassy state) have been studied.End-group (CCl3COO-) vibrations have been assigned by referring to the previous results for methyl and ethyl analogs and four methylene band progressions have been analyzed.Interaction between methylene and end-group vibrations is discussed.It is suggested that in the crystalline state the nP-TCA (n=2) molecule takes a gauche conformation only in O-CH2-CH2CH3 group and the other R'-TCA molecules adopt the all-trans extended form relative to skeletal rotational axes.
ADDITION OF ESTERS OF CHLOROACETIC ACIDS TO 1,3-BUTADIENE CATALYSED BY COPPER COMPLEXES
Vit, Zdenek,Hajek, Milan
, p. 1280 - 1284 (2007/10/02)
The addition of alkyl trichloro- and dichloroacetates to 1,3-butadiene catalysed by copper complexes has been studied.The reactivity of the chloroacetates increased with increasing number of chlorine atoms in their molecule and with decreasing number of the carbon atoms of the alkyl of their ester group.The addition of trichloroacetates gave the products (1 : 1 adducts) in around 80 per cent yields while the less reactive dichloroacetates afforded the adducts in 35percent yield.The 1 : 1 adducts were the products of both 1,4- and 1,2- addition, the relative proportion of which depended especially on the type of the ligand of copper complexes.
KINETICS OF THE NONCATALYTIC REACTION OF TRICHLOROACETYL CHLORIDE WITH 1-BUTANOL IN TOLUENE AND OF THE REACTION CATALYZED BY CARBOXYLIC ACIDS
Semenyuk, G. V.,Razumova, N. G.,Oleinik, N. M.
, p. 25 - 29 (2007/10/02)
The kinetics of the reaction of trichloroacetyl chloride with 1-butanol were investigated in pure toluene and also in the presence of additions of acetic acid and its derivatives.The catalytic activity of the carboxylic acids decreases with increase in their acidity, and the rate constants are described by the Taft equation.The negative value of the reaction constant, consistent with catalysis of bifunctional nature, indicates that the basic center of the bifunctional catalyst has a predominating role in the case where the elimination of the leaving group in the transition state is hindered.
