The absorption, translocation and metabolism of a new
herbicide, n-propyl-C¹⁴ N, N-di-n-propyl-thiolcarbamate (PDPC), were
studied in both peanut and soybean plants. These studies were
carried out on plants of different ages and treated at two rates of
application. The residue content of the plants was also determined
from germination to...
PART I. A chemical examination of the materials toxic to fish in
kraft pulp mill wastes has been made as part of a water pollution
study. Thirty gallons of "foul condensate" from a typical kraft mill
gave 14 g of organic material when extracted with methylene chloride,
and an additional...
Diffusion of short chain n-alkanes was found to be faster in the
polydimethylsilicone elastomer SE-30 than in the polydimethylsilicone
oil SF-96-2000. The opposite was true for the longer chain n-alkanes
suggesting that choice of stationary phase for gas chromatography
would depend on the chain length of sample components. The dependence...
A preparative method for a new compound n-octadecylcycloazadi-boron (CAB), in high yield has been developed. CAB was isolated as
an intermediate in the octadecylamine-catalyzed hydrolysis of pentaborane.
The most probable structure of CAB can be regarded as a
derivative of the three membered ring cycloazadiboron with a
n-octadecyl group substituted...
The reaction of certain purin-8-ols with phosphorus
oxychloride and N,N-diethylaniline are described.
9-Amino-6-chloropurin-8-ol monohydrate reacted with
phosphorus oxychloride and N, N-diethylaniline to yield
the phosphorus oxychloride adduct. Other purin-8-ols
were prepared and the production of analogs similar to
the previously mentioned adduct was attempted.
6-Chloropurin-8-ol and 6, 9-diaminopurin-8-ol hydrochloride
monohydrate...
Although 4- and 5-diacetamidopyrimidines have been reported
in the literature within the past eleven years, it was not until 1965
that a 2-diacetamidopyrimidine was reported. The current investigation
was undertaken to determine whether other 2-diacetamidopyrimi-dines could be synthesized and what the effect of various nuclear substituents would be on the...
