The company says two people were exposed to the nontoxic chemicals methyl iodide and picoline, and the injured person was hurt by broken glass.

In its synthesis 1,000 grammes of picoline were first converted into alphapicoline, 380 grammes being obtained.

Pyridine, picoline, lutidine, and collidine, the first four members of the pyridine series, have, moreover, all been formed synthetically, although the processes are not such as would yield the products as cheaply as they can be gotten from Dippel's oil.

When nicotine vapor is passed through a red-hot tube, it yields essentially collidine, and, with this, some pyridine, picoline, lutidine, and gases such as hydrogen, marsh-gas, and ethylene.

In smoking, some of the nicotine is decomposed, forming pyridine, picoline, and other poisonous alkaloids.
