Abstract
The results of the analysis of calibration mixtures of formaldehyde and methanol in nitrogen with a device for vapour-phase analysis with dosing loops of 5-20 cm 3 in volume and conditions of the analysis providing compact sample injection from loop to the analytical column are presented. The analysis data of low molecular organic compounds by means of the device for vapour-phase analysis with a dosing loop of 15 cm 3 on the analytical column with polyphenylchinoxaline are given. It is shown that the plywood contains methanol in 7-8 times more in comparison with formaldehyde and methylal was not detected, indicating on its decomposed in pressing plywood. The urea-formaldehyde resin contains methanol in 2.4 times and methylal - in 3.6 times more as compared with formaldehyde content. In simulated conditions at saturation 0.4 and 1.0 m2/m3 the plywood liberates formaldehyde above the permissible level to 2.2-8.0 times .
