On May 7, 1997, Maham, Yadollah; Hepler, Loren G.; Mather, Alan E.; Hakin, Andrew W.; Marriott, Robert A. published an article.Recommanded Product: 2,2′-(tert-Butylazanediyl)diethanol The title of the article was Molar heat capacities of alkanolamines from 299.1 to 397.8 K. Group additivity and molecular connectivity analyses. And the article contained the following:
Molar heat capacities were measured for 14 alkanolamines at 5 sep. temperatures between 299.1-397.8 K. The compounds studied were: RR1NCH2CH2OH (R = H, Me, Et, Pr, CH2CH2OH; R1 = H, R, Me2CH, Bu, Me3C, CH2CH2OH) and H2NCMe2CH2OH. Molar heat capacities of these compounds show a structural dependence, where the molar heat capacity of 1 mol. may be considered as the sum of various group contributions. Hence, the reported molar heat capacity data were used as input to a group-additivity anal. that yields estimates of CH2-, OH-, NH- and N-group contributions to molar heat capacities at each temperature studied. The additivity principle was explored in more detail by using mol.-connectivity indexes to obtain a simple 5-term equation that models the molar heat capacities of these alkanolamines over the entire exptl. temperature range. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).Recommanded Product: 2,2′-(tert-Butylazanediyl)diethanol
