Question

2. You work for a company that uses propylene dichloride in a process and arrives in your plant in railcars. During a Management of Change (MOC) review, one of the operators notes that the company you receive the propylene dichloride from sometimes uses aluminum railcars for other products. The question is posed: what would happen if the supplier shipped the propylene dichloride in an aluminum railcar and it sat for a few days before being unloaded into your process? Use the chemical reactivity worksheet (CRW) as a resource to determine if this will be a problem

Explanation / Answer

Propylene di chloride at normal temperature is stable for aluminium but in case of high temperature and humidity it forms hydrochloric acid which can attack aluminium that's why stabilisers like formamide are added to prevent metal
