Abstract (2. Language): 
A new method was experimented for chemical analysis of insoluble acids contained in wood. It is based on the reaction of wood acids with aqueous sodium acetate to liberate an equivalent amount of acetic acid, pH titration of which gives the total acid content. The results of this research for adhesive bonding of wood are pointed out.

Abstract (Original Language): 
Bu araştırmada ülkemizde yetişen bazı önemli ağaç türleri odun-larındaki suda çözünen ve çözünmeyen asit miktarının kimyasal analizler yardımıyla saptanması amaçlanmıştır. Araştırma sonucunda elde edilen bulgulara göre; odundan ekstrakte edilemeyen asitin, üre formaldehit polikondenzasyon reaksiyonunun katalizinde önemli bir rol oynadığı ve odunda bağlı olan bu asit grupları varlığının dikkate değer ölçüde önemli olduğu belirlenmiştir.
