ZT-lie physical coast=ts of the phosphorous acid esters listed be-
low are of interest, because compounds of this ^eneral type may exhib-
it specific toxic properties or serve as intermediates in the prepara-
tion of toxic compounds. This refers to a potentiality rather than M.
actual intention on the part of the Russian investigators. No actual
intention to conduct work with the view of synthesizing toxic crmpounds
has been mentioned in the article
In order to determine the pjssibility of applying the group-correction method
used in the case of five- and six-membered rings of carbocyclic compounds to the
calculation of the parachora of heterocyclic compounds as well, the parachors of
a number of cyclic esters of carbonic, sulfurous, and phosphorous acids were com-
puted.
The group method (in which the parachors of individual groups of a ring are
simply added) was found to be comp'.etely applicable for
five-u and. six-membered
and
heterocyclic rings containing an atom of oxygen, oxygen
phosphorus in the ring.
The group values were determined for the parachors of the following groups
contained in the rings:
