INVESTIGATIONS IN THE FIELD OF UNSATURATED COMPOUNDS. XIII. ANOMALOUS CHLORINATION OF 1,2,4-TRICHLORO-2-BUTENE IN THE PRESENCE OF FERRIC CHLORIDE

It was shown that the low-temperature (-5 to 25 deg C) chlorination of 1,2,4-trichloro-3-butene with chlorine in the presence of anhydrous ferric chloride and tert-butylpyrocatechol leads to the formation of an anomalous reaction product and an addition product .It was found that the composition of the products from the chlorination of 2,3,4-trichloro-1-butene is close to the composition of the products from the reaction of 1,2,4-trichloro-2-butene with chlorine.

Kinetics of Cl(2PJ) Reactions with the Chloroethanes CH3CH2Cl, CH3CHCl2, CH2ClCH2Cl and CH2ClCHCl2

The kinetics of the reactions Cl(2PJ) + RHCl -> RCl + HCl were investigated over the temperature range 257-426 K for RHCl = CH3CH2Cl (k2), CH3CHCl2 (k3), CH2ClCH2Cl (k4), and CH2ClCHCl2 (k5).Cl(2PJ) was produced by 355 nm pulsed laser photolysis of Cl2 and monitored by time-resolved resonance fluorescence spectroscopy.The data are adequately described by the following Arrhenius expressions (units are cm3 molecule-1 s-1, errors are 2? and refer to precision only): k2=(2.34+/-0.42)E-11exp, k3=(8.19+/-1.84)E-12exp,k4=(2.21+/-0.51)E-11exp, and k5=(4.88+/-1.41)E-12exp.Under some experimental conditions evidence for Cl(2PJ) regeneration via a secondary reaction was observed.At 258+/-1 K, deviations of Cl(2PJ) temporal profiles from first-order behavior were attributable to the reactions RCl + Cl2 -> RCl2 + Cl(2PJ)(kj).By modeling the observed C(2PJ) temporal profiles, we found the rate constant kj to lie in the range (5-12)E-14 cm3 molecule-1 s-1 for all RCl investigated.The reactivity trends observed in reactions of Cl2PJ) with C2HXCl(6-x), x=3-6, are discussed.
