  1. A kinetic study of the base catalyzed esterification of propionic anhydride with isopropyl and n-propyl alcohols using a high frequency oscillometer

    … 1951), and rates for the hydrolysis of lower aliphatic esters and esters of chloracetic acid have been measured (Elving 1954; Flom and Elving 1953).</p> <p>The published kinetic -studies using this type instrument have been done in aqueous solution. The principle instrumental effect in these …

    … temperatures. Poly(sulfobetaine)s derived from aliphatic esters show higher UCST-type transition temperatures than their analogs featuring cyclic ammonium cations. The UCST-type transition temperatures increase markedly with spacer length separating the cationic and anionic moieties from 3 to 4 …
