"During the spring of 1919 we undertook to prepare tri-methyl-amine for the Research Department of the Eastman Kodak Company in the Industrial Chemistry Laboratory of the Missouri School of Minds. According to V. Merz and K. Gasiorowski the three methyl amines were qualitatively proven to be present in the reaction products obtained by heating methyl alcohol, ammonia and zinc chloride to 220°C. in a bomb for fourteen hours. As these raw materials are inexpensive we attempted to prepare the tri-methyl-amine by this reaction employing for the purpose a small industrial autoclave. Methyl amines were obtained by the yield especially of the tri- were very low (less than one percent) and the process was put aside until such time as smaller scale experimental work could be done upon it. The researches to be described in this paper were undertaken to supply the need outlined above" – p. 3.
