摘要:
AbstractSome 4,4′‐diformyl‐α,ω‐diphenoxyalkanes have been prepared by reacting the sodium salt of p‐hydroxybenzaldehyde with α,ω‐dibromoalkanes. These compounds were oxidised by alkaline potassium permanganate solution to the corresponding α,ω‐diphenoxyalkane‐4,4′‐dicarboxylic acids. The diformyl compounds were reacted with malonic acid yielding acrylic acid derivatives which have the melting‐point characteristics of mesomorphic substances. Hippuric acid has been shown to condense readily with the diformyl products yieldi

摘要:
AbstractThe action of cyclohexylamine on 1‐chloro‐2‐nitrobenzene, 1‐chloro‐4‐nitrobenzene, 1‐chloro‐2,4‐dinitrobenzene, and 1‐chloro‐2,4,6‐trinitrobenzene has been investigated. The nitro‐cyclohexylaminobenzenes so found were nitrated and 2,4,6‐trinitrophenylcyclohexylnitramine, a colourless explosive product, similar to 2,4,6‐trinitrophenylmethylnitramine or the well‐known

摘要:
AbstractThe exact quantitative derivation of theGibbsformula, relating the adsorption of the solute at the interface of a solution with another phase to the change in interfacial tension (free energy of the interface) as the concentration of the solute varies, requires a thorough knowledge of thermodynamics.For instructural purposes and for better understanding the foundations of the equation it seems worth while to look for a qualitative demonstration.It appears, that it is impossible to prove the law expressed by the equation, in quite the same manner in the two cases of positive and negative adsorption. But a fictitious process to produce one cm2of the actual surface can be devised which consists of two steps and is applicable to both cases, if only the order of the two steps is reversed.This demonstration is based on the properties of the particles (molecules or ions) of the solute, which influence both the sign of the adsorption positive or negative) and the change of the surface tension.
