Abstract

The present studies were performed to see the influence of alkyl amines on the growth of 0.3 molar sodium lauryl sulphate micellar solutions at 303 K, 313 K and 323 K. In the present study ethylamine and n-tributyl amine were used. The results are interpreted and reported with the help of ultrasonic velocity and absorption studies.

Abstract

Ultrasonic velocity studies were undertaken on solutions of cellulose acetate phthalate in alkali metal hydroxides LiOH, NaOH and KOH and water mixture in the concentration range 0-2.5% by weight at frequency of 3 MHz in three different temperatures, 303 K, 313 K, 323 K. The observed non-linear increase in ultrasonic velocity with increase of cellulose acetate phthalate concentration is attributed to the polymer-ion interaction in higher electrolytes.
