- Executive summary:
The DSC method is mentioned in the EU guideline. Allthough this guideline is not mentioned in the report, DSC is a well accepted method for determining non explosive properties.
Diethylaluminum chloride is non explosive because it has a decomposition heat of 366 J/g, which is lower than 500J/g.
Diethylaluminium chloride has two Al-ethylgroups and has thereby around 2 times higher decomposition heat than ethylaluminium dichloride with oneAl-ethylgroup. AlCl3 with 0 Al-C groups is a non energetic substance, so the decomposition heat is 0J/g.
The Al-C content is reponsible for the energy deliverance.The Al-C content is lower in dichloroisobutylaluminium than in ethylaluminium dichloride, so the decomposition heat of dichloroisobutylaluminium will be lower than the decomposition heat of diethylaluminium chloride.
In other words: the decomposition energy of isobutylaluminiumdichloride will be lower than 366 J/g.
So dichloroisobutylaluminium is non explosive too.
Reference
No leakage was detected by measuring the weight of the pan before and after the experiments. The onset temperature of the exothermal effect is 328°C.
Total heat of decomposition is 366 J/g. So diethylaluminum chloride has a decomposition energy lower than 500 J/g, wich indicates diethylaluminum chloride has no explosive properties.
