11. Newer parameters have thus been derived from water-1-octanol partition coefficients or other similar data. 12. Long chain aliphatic hydrocarbon alcohols and aldehydes like 1-octanol and octanal are second important group of substances. 13. It is classified as an ester that is formed from 1-octanol ( octyl alcohol ) and acetic acid. 14. The original formula is given first followed by a revised formula which takes a different assumption of complete miscibility in octanol . 15. While many hydrolyzable tannins and most condensed tannins are water-soluble, several tannins are also highly octanol -soluble. 16. Tests of repeated bolus dosages of 1-hexanol and 1-octanol showed potential for CNS depression and induced respiratory distress. 17. For nonionic organic contaminants, the K OC can be determined based on the octanol -water partition coefficient ( K OW ). 18. Used widely in pharmaceutical research, LogD is the logarithm of the " true " partition coefficient of a compound between octanol and water. 19. For example, rainbow trout exposed to two narcotics, MS-222 and 1-octanol exhibited a variety of respiratory-cardiovascular responses. 20. Many other isomers are also known generically as octanols . 1-Octanol is manufactured for the synthesis of esters for use in perfumes and flavorings.
