1, This reaction involves disproportionation of the aldehyde.

2, The deactivation kinetics for the vapor-phase disproportionation of toluene over mordenite catalyst has been studied by using a combined unit of micro-reactor under pressure and gas chromatography.

3, In toluene disproportionation, the catalytic activity is effected by the acidity and crystal size of catalyst.

4, The p-xylene selectivity of toluene disproportionation reaction on deactivated HZSM-5 increases with the increase of coke content.

5, More p-xylene may be obtained by disproportionation and isomerization of alkylbenzenes.

6, The filming on steel using the disproportionation reaction of sub - sulphide of Al was studied.

7, A pulse technique is applied to kinetic study for disproportionation of toluene on mordenite catalysts.

8, The results showed that the cross - linked clay had better catalytic activity to the disproportionation of 1,2,[http:///disproportionation.html] 4 - trimethylbenzene.

9, Toluene can be used for gasoline blending components, solvents and through disproportionation and transalkylation of benzene and xylene system, and a variety of synthetic organic chemicals.

10, The application of soft sensor and advanced process control technology in aromatics disproportionation unit is introduced.

11, A second destabilizing mechanism is Ostwald ripening, also known as coarsening or disproportionation, whereby gas diffuses from smaller to larger bubbles.

12, Nano - Ni was first used as catalyst for disproportionation of resin acid.

13, Ni-loaded nanocatalyst has been prepared by means of metal alkoxide hydrolysis. The lifetime of the catalyst for catalyzing disproportionation of gum rosin is investigated.

14, The semiquinone radical of TS as reduction product existed stably on CPE, which might be that hydrophobic organic phase inhibited the disproportionation reaction of the radical of TS.

15, Authors carried out an experiment to investigate effects of the mixed rosin on disproportionation.

16, A superconductor with very low content of sodium and very high content of hydronium through a disproportionation reaction route is reported.
