The maximum endothermic peak temperature which is observed 97PROBLEM TO BE SOLVED: To provide a polyketone fiber having a high retention of an elastic modulus at an elevated temperature and a low heat shrinkage percentage.森田 徹谷口 龍
When ammonium chloride dissolves in water, the absorption of heat occurs shows the reaction is an endothermic reaction. So, in the endothermic reaction, when the temperature increases, the value of the equilibrium constant also increases. Thus, the solubility of ammonium ch...
