CORRELATION OF FIRE HAZARD CHARACTERISTICS WITH CHEMICAL STRUCTURE. XVI. á,ù-AMINOALCOHOLS

It is performed QSPR research in number of normal ,-aminoalcohols. It is shown possibility of applying the carbon rule for prediction physicochemical and fire-dangerous properties of aminoalcohols. Empirical relationships for prediction heat of vaporization (Hv), heat of formation (Hf ), critical pressure (Pc), critical temperature (Tc), boiling point (TB) and flash point (FP), lower and upper flammability limits (LFL, UFL) are found depending on number of carbon atoms (NC): Hv = 42,991NC 0 1304 , (1  NC  6); Hv = 2,138NÑ + 37,43 (7  NÑ  13); Hf = – (20,641NC + 161,78) (1  NÑ  13); Pc = –0,0268NC 3 + 0,921NÑ 2 – 12,508NÑ + 83,94 (1  NC  13); Tc = –0,494NC 2 + + 23,25NÑ + 532,3 (1  NÑ  13); TB = 0,1606NC 3 – 3,5018NC 2 + 34,532NÑ + 386,1 (1  NÑ  13); TB = 8,457Ív + 43,7 (3  NÑ  13); FP(K) = –0,319NÑ 2 + 9,046NÑ + 349,3 (1  NÑ  12); LFL = 4,0985NÑ 0 816 , (1  NÑ  13); UFL = 35,237NC – , 0 814 (1  NÑ  13). The modified Ormandy – Craven's formula are upgraded by using data of normal ,-aminoalcohols. It is FP(°C) = 0,394TB – – 26,5
