Key result

Remarks on result:

other: Chemical (CAS no. 71230-67-6) ignites only when the flame of bunsen burner having temperature of 950°C is brought in contact with it.Thus it can be concluded that substance is flammable only at high temperature of about 950°C.

Conclusions:

Dipotassium 4,4'-bis[6 -anilino-4 -[bis(2 -hydroxyethyl)amino-1,3,5 -triazin-2 -yl]amino]stilbene-2,2'-disulphonate did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that  Dipotassium 4,4'-bis[6 -anilino-4 -[bis(2 -hydroxyethyl)amino-1,3,5 -triazin-2 -yl]amino]stilbene-2,2'-disulphonate is not auto-flammable.

Executive summary:

Dipotassium 4,4'-bis[6 -anilino-4 -[bis(2 -hydroxyethyl)amino-1,3,5 -triazin-2 -yl]amino]stilbene-2,2'-disulphonate did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that  Dipotassium 4,4'-bis[6 -anilino-4 -[bis(2 -hydroxyethyl)amino-1,3,5 -triazin-2 -yl]amino]stilbene-2,2'-disulphonate is not auto-flammable.
