β¦ Synopsis
The reaction rates of atomic boron with various epovrdes have been measured m a Row tube appnratus. The btmolrcular rate constants, in umts of cm3 molecule-' s'-' ,are l,Z-zpo~ypropane (8.6 X IO-t'), 1,2~poxybutanc (8.8 x IO-"), 1,2,3,4drepo\ybutanc
(5.5 X IO-").
I-chloro-2.3epouypropane (5.7 X IO-"),and 1,2spoxy-3.3,3-tnchoroptopsne
(1 5 x 10-i').

## Abstract The photooxidations of __n__βbutyraldehyde initiated by Cl atom were carried out at room temperature (298 Β± 2K) and 1 atm pressure. The rate coefficient for the reactions of Cl atom with __n__βbutyraldehyde was determined as __k__ = (2.04 Β± 0.36) Γ 10^β10^ cm^3^ molecule^β1^ s^β1^ by us
