The action of ethylamine on cellulose: Part III—The formation of cellulose III and its infra-red spectrum between 1500 and 650 cm−1

摘要: Abstract When the amine is removed from ethylamine-treated bacterial cellulose films by washing with hexane or chloroform, formation of III can occur even before are allowed to dry. The I accompanied some changes in band frequencies infra-red spectrum between 1 400 and 000 cm−1, these show up more clearly spectra than those fibres.
