Methanol forms adducts with $\ce{CaCl2}$ but I am not finding much information about the nature of these adducts & their stability. Are these solid adducts? Crystalline? Is the reaction substantially exothermic etc.?
At temperatures below 55°C, $\ce{CaCl2}$ forms $\ce{CaCl2·4CH3OH}$ with methanol and below 55°C, $\ce{CaCl2·3CH3OH}$ is formed.
