β¦ Synopsis
The photoinduced decomposition of aqueous formaldehyde in air-free solutions, some saturated with CO, was investigated. The initial quantum yield of aldehyde decomposition, Qi(-HCHO), strongly depends on the substrate concentration.
The presence of CO in the solution essentially diminishes the aldehyde decomposition because of back reactions. The quantum yields of the final products, glyoxal and carboxylic acids (formic and oxalic), are determined under various experimental conditions. A probable reaction mechanism is presented in accordance with the results.

Kinetic equations for the decomposition of S-hydroxymethyl cellulose xanthate in the presence of acid and formaldehyde are derived. The assumed mechanism involves an equilibrium between the 8-hydroxymethyl cellulose xanthate and cellulose xanthic acid and xanthate ion. Decomposition appears to proce
## Abstract Intrinsic viscosities were determined for solutions of CMG in pure water and 0.9 wt.β% aqueous NaCl. To avoid the 0/0βtype extrapolation typical for Huggins plots, a new procedure was used. For CMG and pure water, this requires only two adjustable parameters: the specific hydrodynamic v
