of the substances present at the start of the reaction. Thus, the heat of reaction determined at constant pressure is also designated theenthalpy of reaction, represented by the symbol ΔH. If the heat of reaction is positive, the reaction is said to beendothermic; if negative,exothermic. ...
1. A method of removing the heat of reaction from continuous exothermic chemical reactions conducted in the liquid phase, which method comprises introducing a fluid which is inert to the reactants and in which reactants and reaction products are preferably insoluble or almost insoluble, and which...
Published estimates of the overall heat of reaction, during the pyrolysis of wood range from q = 370 J/g (endothermic) to q = −1700 J/g (exothermic). Data from differential thermal analyses show that the pyrolysis of lignin is more strongly exothermic than that of cellulose; this is ...
hydrogen reduction of a reaction gas including a silane gas, which comprises introducing hydrogen chloride into a reactor in addition to the reaction gas and utilizing within the reactor the heat of reaction generated from the reaction between the hydrogen chloride and silicon as an additional heat ...
