Excess volumes of chloroform and bromoform mixtures with some n-alcohols at 303.15 K

Abstract

Excess volumes of binary mixtures of chloroform and bromoform with the following n-alcohols: methanol, ethanol, and n-propanol have been measured as a function of composition at 303.15 K by a dilatometric method.

Densities, viscosities, and ultrasonic velocity studies of binary mixtures of trichloromethane with methanol, ethanol, propan-1-ol, and butan-1-ol at T=(298.15 and 308.15)K

“…For the binary mixtures of CHCl 3 + C 2 H 5 OH, V E values are negative for lower values of x 1 (ethanol rich region) and positive for higher value of x 1 (trichloromethane rich region). This type of behaviour for CHCl 3 + C 2 H 5 OH was also reported by Singh et al [12] whereas the V E values are positive for the whole composition range in the system, trichloromethane with propan-1ol and butan-1-ol. With higher alkanols (C 3 -C 4 ) the geometrical contributions, clustering, extent of H-bonding and proton donating ability decreases, thus positive V E values are observed for mixtures of trichloromethane with higher alkanols.…”

Thermophysical properties of binary mixtures of odichlorobenzene and o-chlorophenol with diethyl ether, tetrahydrofuran, cyclohexane and anisole

“…For binary mixture of OCP + DEE, OCP + CH and OCP + ANS, V E values are positive for low values of x 1 (OCP low region) and negative for higher values for x 1 (OCP rich region). Similar behaviour was also reported by Singh et al [31]. The positive values of V E arise due to the breaking or stretching of H-bond in the self associated OCP and physical dipole-dipole interaction between the molecules.…”

Reactions of α‐Diazoketones with Indolinone Imines: Synthesis of New 1,3,3‐Triaryl‐1′‐methylspiro[azetidine‐2,3′‐indoline]‐2′,4‐diones.

“…However, the reactions of ketenes with ambident substrates often depend on the electronic and steric environment around the particular functional group. The reaction of diphenylketene with benzil monoimines occurs at C=N group in preference to the C=O group [4]. Similar reactions of ketenes with benzophenone N-phenyl hydrazone [5] and with fluorinone N-benzoyl hydrazone [6] are reported to occur at N-H bond and C=N bond, respectively, forming N,N-disubstituted hydrazones and 2azetidinones.…”

“…The 2-azetidinones are biologically important compounds [12]. It is worth mentioning that only a few stable spiroazetidinones are reported in the literature [4,8,[13][14][15]. .…”
