1. INTRODUCTION. 
The following items were briefly discussed with Dr. Klebert at 
Leverkusen. 
a. Thionylchloride (SOCl?). 
The I. G. at Leverkusen shipped to Aramendorf (be- 
tween Halle and Merseburg) for manufacture of poison gas. Ammen- 
dorf was said to have been a station for gas manufacture during 
war of 1914-16. The capacity of the SOCI2 plant at Leverkusen is 
140 tons per month and up to 90 tons per month were shipped to 
Amrnendorf. Shipments to Ammendorf during war years were as 
follows; 
1938 21 tons 1942 600 tons 
1939 170 " 1943 700 " 
1940 440 " 1944 220 « 
1941 645 ” 1945 
b. Protection Against GNC1. 
Considerable research work was done at Leverkusen in 
an attempt to find a satisfactory agent for use in gas mask can- 
isters against CNCl. General method of approach in experiments 
was to seal CNCl in ampoules with various agents and analyze for 
CNCl decomposition after a time. The work was said to have pro- 
duced no worthwhile results, 
c. Tear Gas. 
Work was done on process for a tear gas, HG00CC1* by 
action of phosgene on methyl fonnate. The phosgene presumably 
acted as a chlorinating agent.

It was stated that this lachrimator was well known 
and that none had 'been produced at Leverkusen during the war. d, Artificial Fog and Its Production. 
The I.G. at Leverkusen developed an apparatus used exclu- 
sively for shore installations by the German Navy for producing 
fogs from mixtures of SO3 and The proportions of the 
ingredients varied with the seasons and were as follows:

The apparatus was manufactured by various small firms to 
drawings and specifications developed at Leverkusen. Prints are 
available at Leverkusen. 
Leverkusen produced the SO3-CIHSO2 mixture for the Navy. 
The capacity was about 750 T per month and production for the 
Navy during the last several years has been as folio*,vs:

e. Colored Smokes. 
Considerable work was done at Leverkusen under the general 
direction of Dr, Klebert on inorganic colored smokes. No tan- 
gible results were obtained and none were manufactured. The pur- 
pose of the smokes was for use in signal corps of German Amy, 
f. Titanium Smokes, 
was a product of Leverkusen and was made up to a number 
of formulae for smoke screens. This plant was put out of opera- 
tion by bombing late in October, 1944*
