Gao, "Influence of [B.sub.2][O.sub.3] and basicity
on viscosity and structure of medium titanium bearing blast furnace slag," Journal of Chemistry, vol.
Alternatively, other techniques include; use of different preparation methods to enhance the metal support interaction, use of bimetallic catalyst systems and addition/incorporation of metal and/or redox oxides as promoters to effect the acidity and/or basicity
The constants of acidity, KA and basicity
, KD of the polymers were obtained by using Eq.
The overall increase in montmorillonite content as well as due to influence of other concomitant minerals (kaolinite, hydromica, zeolite) surface basicity
of the samples raised about two times and surface acidity by 1.5 times.
The strong basicity
of PS is due (in part at least) to the way of N atoms to stabilize H+ of the acid form by forming a strong hydrogen bond.
Key words: acid neutralization; basicity
; calcium phosphate cement; endo-materials; mineral trioxide aggregate; setting time; tricalcium silicate.
The quantities of the carboxyl groups, the combined acidity of the 3 functional groups (carboxyls+lactones +phenols), total surface acidity (carboxyls + lactones + phenols + additional acidic species), and surface basicity
of the biochars are presented in Table 5.
Therefore, the variation of the basicity
of the slags is based on the evaluation of the static state of the solidified melt.
de Nice-Sophia Antipolis-CNRS, France) should allow for the judicious choices of a few reference Lewis acids in order to construct Lewis basicity
scales that cane be used as a general guide to basicity
The steric shielding of the free electron pair in the nitrogen atom of the amine and its reduced basicity
enhance its effectiveness as a stabilizer.
