Acidic behavior of chloroform

Aggregation behavior of rodlike ionogenic polymers in chloroform.

The rodlike ionogenic polymers poly(p-pyridylene-phenylene) and poly(p-pyridylene/phenylene-ethynylene) form polyelectrolytes when protonated with toluene sulfonic acid or ethane sulfonic acid in chloroform solution. This molecular modification, clearly indicated by a marked red shift of the UV absorption band, induces the formation of prolate, bundlelike aggregates, whose size and shape are ob...

Anomalous Solubility Behavior of Several Acidic Drugs

The “anomalous solubility behavior at higher pH values” of several acidic drugs originally studied by Higuchi et al. in 1953 [1], but hitherto not fully rationalized, has been re-analyzed using a novel solubilitypH analysis computer program, pDISOL-X TM . The program internally derives implicit solubility equations, given a set of proposed equilibria and constants (iteratively refined by weight...

Chloroform

It was perhaps fitting that Lieut.-Colonel Edward Lawrie, should signalise the year of his retirement from the post of R,esidenc\r Surgeon at Hyderabad by the publication of a volume on Chloroform, a subject with which he has been identified for many years past, and in defence of his views on which, and those of his master Syme, he has fought non sine gloria for many }7ears. The introduction to...
