Show EXPERIMENTAL CONDITIONS Of critical importance in the modelling of compounds like CH^Cl^ is the accurate and detailed acquisition of experimental data. Such compila tions become very difficult when studying compounds like the chlorinated methanes. Factors which contribute to the complexity of the experimental procedures include: 1. The extremely corrosive nature of the CH9C1 system under flame mode conditions, 2. The need to supplement the CH9C1 flame with another fuel in order to attain stable flame conditions, 3. The unstable nature of the CH9C19 flame system under subatmos-pheric conditions and 4. The number, variety and highly reactive nature of some stable intermediate products which are generated during the flame mode combustion of CH?C1 type systems. All of these complexities combine to make the study of the CH CI system very difficult. Since CH9C19 and air will not result in a stable flame at atmospheric conditions, and since methane (CH.) is the analogous hydrocarbon of the chlorinated methanes, it was decided early in the study to investigate CH,/CH^Cl0/air systems. The addition of CH. however to the CH_C1. H 2 2 4 2 2 system complicates analysis substantially since "pure" CH CI combustion chemistry is difficult to infer. Indeed, the specific comparison of the CH./CH»Cl-/air system with other "analogous" systems becomes difficult 4 2 2 resulting in the need to reformat the data (see references 6, 7 for more discussion regarding this difficulty). This paper will make no attempt to overcome these complexities and only presents the data in basic form which is suitable for general comparisons. 5.3.6 |
