7Germany Led the Race
- Petroleum
- Coal Tar
- We smell it near coke ovens
- We smell it in seal-coat for the driveway
8Chemicals From Base Substances
- Benzene
- Toluene
- Xylenes
- Ethylbenzene
- Phenol
9Benzene
10Organic Structures

Ethyl Benzene
11Xylenes
12Aniline
Adolf von Baeyer Craked the chemical code for
aniline.
13Naphthalene
14Chlorinated Hydrocarbons
Chlordane
This is very similar to ethyl chlorohydrin, a
precursor to chemical mustard.
15Thiodiglycol
HO-CH2-CH2-S-CH2-CH2-OH
Ethyl chlorohydrin, reacted with sulfur creates
this molecule.
In 1886 Victor Meyer, unaware, created mustard
thiodiglycol by adding 2 simple Cl atoms
16Mustard Thiodiglycol

IPS INCHEM
18Ypres, April 22, 1915
- Cl2
- Organized by Fritz Haber
- Employed 5730 cylinders
- Release zone 6 km long
- 800/2000 casualties
19PPE
At first, rags, soaked in urine or bicarbonate
were used to neutralize chlorine. By the end of
1915 more efficient masks and supplemental oxygen
began to become available.
20Delivery
Early chemical attacks employed pressurized
cylinders and gases were released in tandem.
This caused logistic problems and
backlash. Later mortars were filled with gas.
The wepon could then be launched with a mortar
cannon such as a Stokes Mortar Gun.
21Other Respiratory Irritants
- Phosgene
- Chloropicrin
- Sn Tetrachloride
- Chloracetone
- Arsine
- HCN
Pulmonary Edema Profuse Secretions O2 Inhibition
22U.S. Finds Success
Americas secret chemical weapon the pesticide
DDT. DDT is largely credited with helping Allied
forces with World War II. What other project
failed numerous times but was finally successful
on account of DDT?
23Nerve Agents

25Bio Review
- Koch Postulates 1986
- Disease not in healthy animal
- Isolate grow in culture
- Must produce disease in animal
- Should be able to be reisolated
26First Program
