THERMAL STABILITY OF ORGANIC COMPOUNDS.

Abstract

One flow and one static pyrolysis apparatus directly attached to a gas chromatograph through a gas sample valve was built and their performance was studied using the four butanols as test substances. A second static pyrolysis apparatus was developed and was partly assembled. Studies were started on the use of a novel principle for building up a thermal shield for adiabatic calorimetry over a wide temperature range. It is based on the use of microconductors consisting of an inner conductor insulated with magnesia within an outer thin-walled metal tube, 0.25 - 1.00 mm in diameter. The mass of the shield consists almost entirely of the leads. The use of two types of microconductors is presently being investigated - one with platinum wire serving as a resistance thermometer and the second with chromel, to be used as a heater. (Author)
