Studies on arsenical creosote as a wood preservative for marine structures. Part 1. Incorporation of arsenic in creosote at various temperatures

摘要

A detailed study of the fortification of normal creosote and low temperature creosote with As sub(2) O sub(3) at 40°C, 50°C, 60°C, 70°C, 80°C and 90°C was carried out. When compared to normal creosote, low temperature creosote has been found to combine more easily with As sub(2) O sub(3) when temperature was . raised from 40 to 90°C. The incorporated arsenic values obtained shows that low temperature creosote with high phenolic content, retains considerably more As sub(2) O sub(3) and a maximum of 0.2180% w/w can be incorporated in low temperature creosote at 90°C.
