Results and discussion

Any other information on results incl. tables

Flammability in Contact with Water The results obtained from the different tests are summarised below.

Test 1 A small quantity of gas was evolved and a white precipitate formed. No ignition was observed.

Test 2 A small quantity of gas was evolved and a white precipitate formed. No ignition was observed.

Test 3 A solid precipitate formed immediately and a small quantity of gas was evolved. No ignition was observed.

Test 4 Some gas evolution was observed with the quantity of gas evolved from each replicate given in the table below. The maximum evolution rate of the gas was 0.1 mL/hour, and on the basis of the chemical structure and the test system it is considered highly likely that the gas evolved is isopropanol. Commensurate with the other tests a white precipitate was formed.
