Propyl aniline

The experimental details for mono-M-propylanillne are as follows. Reflux a mixture of 230 g. of aniline and 123 g. of n-propyl bromide for 8-10 hours. Allow to cool, render the mixture alkafine, and add a solution of 150 g. of zinc chloride in 150 g. of water. Cool the mixture and stir after 12 hours, filter at the pump and drain well. Extract the thick paste several times with boiling light petroleum, b.p. 60-80° (it is best to use a Soxhlet apparatus), wash the combined extracts successively with water and dilute ammonia solution, and then dry over anhydrous potassium carbonate or anhydrous magnesium sulphate. Remove the solvent on a water bath, and distil the residue from a Claisen flask with fractionating side arm (well lagged). Collect the n-propyl-aniline at 218-220° the yield is 80 g. Treat the pasty solid zincichloride with an excess of. sodium hydroxide solution and steam distil 130 g. of pure aniline are recovered. 

Bei der Reaktion von Diisopropylamin mit l-Chlor-2,4-dinitro-benzol in Benzol bei 60° entsteht das erwartete N,N-Diisopropyl-2,4-dinitro-anilin nur in sehr geringer Ausbeute als Hauptprodukt entsteht das nur eine Isopropyl-Gruppe enthaltende 2,4-Dinitro-N-iso-propyl-anilin neben einer geringeren Menge an 2,4-Dinitro-N propyl-anilin1. Ahnliche Er-gebnisse erhalt man mit dem entsprechenden Aryl-fluorid und -bromid sowie bei Durch-fiihrung der Reaktion in Methanol oder Dimethyl-sulfoxid.

The gel (%) and polymerization (O) times of unsaturated polyester containing a fixed initial concentration (in mol/L) of benzoyl peroxide and aryl-substituted N,N-bis(3-allyloxy-2-hydroxy-propyl)aniline versus the (t+ value of the aryl substituent of the amine. The symbols (A, A) indicate the corresponding time values for the analogous N-substituted 2-naphthylamine which in the usual sense is not a substituted aniline. (Time values from Refs. 24 and 25 (t+ from Ref. 23, except for (t+ value for 2-naphthyl (—0.61), recalculated from Bier (64).)...

These considerations are exemplified by the efficiency of intramolecular fluorescence quenching of N,N-dimethyl-4-[3-(l-pyrenyl)propyl]aniline (PID.) as studied in the isotropic and cholesteric phases of M(38). The mechanism for (non-eraissive) exciplex formation could be accommodated in both phases to Scheme 2. 

Figure 31. Gauche and trans conformations of p-propyl aniline. These illustrations are the result of structural optimization using a molecular mechanics computer program. Atoms were drawn (not to scale) in order to improve spatial perspective.

To further explore the temporal behavior of trans-propyl aniline v, emission, a time-gating experiment was performed Dispersed fluorescence spectra were obtained with acquisition of signal limited to the time range indicated in Fig. 35. The spectral range shown corresponds to 775—1850 cm"1 on the energy scale of Fig. 34. The comparison of short- and long-time emission... 

Of considerable importance are the alkanolamines. Some of these such as Quadrol (see Di- and Polyhydroxy Components) have been mentioned previously. Other di- and trialkanolamines used include triethanolamine, bis(2-hydroxyethy1)- and bis(2-hydroxy-propyl)aniline, and bisalkanol derivatives of piperazines. Similar derivatives that are commercially available include JV,Af, Af -tris(2-hydroxyethy 1 )isocyanurate (Allied Chemical Corp.), A, Af -[bis(2-hydroxyethyl)]diraethy Ihydantoin (Glyco Chemicals Co.), and dimethylolpropionic acid (International Minerals Chemicals Co.).
