The process for preparing an alkyl hydroxyalkyl cellulose ether comprises the
steps of: a) alkalizing cellulose to obtain alkali cellulose, b) reacting alkali
cellulose with an alkyl halogenide until an alkyl cellulose ether with a D.S.(alkyl)
value of from 0.7 to 2.5. is attained, c) removing excess alkyl halogenide from
the reaction mixture, and d) reacting the alkyl cellulose ether with an alkylene
oxide in a liquid suspending agent to produce an alkyl hydroxyalkyl cellulose ether.
An alkyl hydroxyalkyl cellulose ether is produced which has an D.S.(alkyl) of from
0.7 to 2.5 and an MS (hydroxyalkyl) from 0.03 to 2.0, wherein not more that 15
percent of the hydroxyalkyl groups are capped with an alkyl group.
