Scientific Work

Craft's investigations were largely in the field of organic chemistry, but his name is connected also with many interesting achievements in physics and in physical chemistry. He invented a new hydrogen thermometer; measured the densities of iodine at very high temperatures; demonstrated an interesting regularity in the variation of the boiling points of chemically allied substances with the external pressure; prepared a number of new compounds of the element silicon, which are interesting because of their chemical resemblance to the corresponding compounds of carbon; and also prepared new compounds of arsenic. But his most important achievement was the discovery, jointly with Friedel, of one of the most fruitful synthetic methods in organic chemistry.

Hundreds of new carbon compounds have been brought into existence by this method (New International Encyclopedia), which is based on the catalytic action of the chloride of aluminium.
