esters were added at the top of the reactor at 1.2 cm3/h (reactor volume ca. 30 cm3), without a carrier gas flow. Products were collected in a trap maintained at dry ice temperature. Product Analysis. Total conversion and the composition of the products were determined by GC using 30 m X 3.2 mm column packed with 23% SP-1700 on 80-100-mesh Chromosorb AAW and DB5 (60 m X 0.25 mm). The deuterium content of each butene isomer was determined using a HP5985A GC mass spectrometer equipped with a 30 m X 0.53 mm bonded Alteck FSOT RSL-160 capillary column and operated a t 10 eV. The isotope composition of butenes were calculated from the area of m/e 56 and m/e 57. Peak m/e (M - 1) was very small (
