Dissolving potassium hydroxide in methanol is significantly faster than sodium hydroxide but it remains a highly exothermic reaction, producing heat and therefore vaporising methanol during dissolution. 'Ready To Use' Methoxide Catalyst is a clean, free flowing solution. Unlike sodium methylates, 28% potassium hydroxide in methanol (Potassium Methoxide) is a concentrated more cost effective product used for the manufacture of biodiesel. The synthesis route is accurately controlled delivering a refined intermediatory. Each kg of 28% solution contains 280g of potassium hydroxide. UN drum included
