| titleOfInvention | Granular or powdery phenol-formaldehyde resin and process for production thereof |
| abstract | A granular or powdery resin which is a condensation product of a phenol and formaldehyde, said granular or powdery resin being characterized byn (A) containing spherical primary particles and secondary particles resulting from the agglomeration of the primary particles, each of the particles having a particle diameter of 0.1 to 150 microns, (B) having such a size that least 50% by weight thereof can pass through a 100 Tyler mesh sieve, (C) having a free phenol content, determined by liquid chromatography, of not more than 50 ppm, (D) having a D 990-1015 /D 1600 ratio of from 0.2 to 9.0 and a D 890 /D 1600 ratio of from 0.09 to 1.0 in its infrared aosorption spectrum measured by a KBr tablet method, wherein D 1600 represents the absorption intensity of an absorption peak at 1600 cm -1 , D 990-1015 represents the highest absorption intensity of absorption peaks at 990 to 1015 cm- 1 , and the D,,, represents the absorption intensity of an absorption peak at 890 cm -1 , and (E) having a weight increase by acetylation of 23 to 40% by weight. n The granular or powdery phenol-formaldehyde resin may be produced by a process which comprises contacting a phenol with a hydrochloric acid-formaldehyde bath containing 5 to 28% by weight of hydrochloric acid and 3 to 25% by weight of formaldehyde with the total concentration of hydrochloric acid and formaldehyde being 15 to 40% by weight, while maintaining a bath ratio, defined by the quotient of the weight of the hydrochloric acid-formaldehyde bath divided by the weight of the phenol, of at least 8, said contacting being effected such that after contacting of the phenol with the bath, white suspended particles are formed and thereafter developed into a pink-colored granular or powdery solid. |
