Mechanism of Reaction of m-Xylene-formaldehyde Resin and Anilines.

Occupational asthma due to formaldehyde resin dust with and without reaction to formaldehyde gas.

We report the cases of three subjects who developed asthma after being exposed to formaldehyde dust or gas. For two subjects, specific bronchial provocation tests with formaldehyde gas did not cause significant bronchoconstriction, whereas exposure to formaldehyde resin dust did. One subject experienced asthmatic reaction after being exposed to formaldehyde resin dust and gas. These findings su...

Preparation and characterization of template-free mordenite type zeolite and comparison of m-xylene isomerization reaction over mordenite and SAPO-11

In this work, Mordenite zeolite was successfully synthesized with Si/Al ratio of 18 in absence of organic template. The hydrothermal method was applied for synthesis under optimum conditions: 24 h synthesis time, 180°C temperature and 2 days aging time. The obtained zeolite was characterized by X-ray powder diffraction (XRD), Brunauer-Emmett-Teller (BET), X-ray fluorescence (XRF), Fourier Trans...
