Latest Patents
One of Kenneth Sundberg's latest patents is a process for the manufacture of methyl cellulose ether. This water-soluble methyl cellulose ether is produced by reacting methyl chloride with cellulose that has been activated through mercerization with aqueous alkali. The reaction occurs in the presence of a C-Calkyl chloride as a reaction medium at temperatures ranging from 65°C to 90°C and pressures between 3 to 15 bar. The weight ratio of cellulose to C-Calkyl chloride typically ranges from 1:1 to 1:5, allowing for efficient production at low pressure.
Another significant patent involves a nonionic cellulose ether, specifically a methyl ethyl hydroxyethyl cellulose ether. This cellulose ether exhibits a flocculation temperature of 70-95°C, with a degree of substitution (DS) for methyl ranging from 0.1 to 0.8 and for ethyl from 0.1 to 0.7. The versatile properties of this cellulose ether enable its use as a thickening agent or rheology modifier in various aqueous formulations, including latex-containing paint compositions.
