Effect of the agitation rate on the generation of low-crystallinity cellulose from phosphoric acid

Autor: Kothari Sanjeev H, Vijay Kumar, Gilbert S. Banker

Publikováno v: Journal of Applied Polymer Science. 82:2624-2628

Changes in the basic powder properties of low-crystallinity powder cellulose (LCPC) as a function of the agitation rate used during its generation from phosphoric acid were investigated. We reacted cotton linter with phosphoric acid (85% w/v) at room

Phosphoric acid mediated depolymerization and decrystallization of cellulose: Preparation of low crystallinity cellulose — A new pharmaceutical excipient

Autor: S. Wei, Gilbert S. Banker, Vijay Kumar

Publikováno v: International Journal of Pharmaceutics. 142:175-181

The reactions of cellulose with phosphoric acid under different temperature conditions were investigated to prepare a new class of cellulose excipients which have controlled, low degrees of crystallinity and reduced levels of polymerization. The resu

Incompatibility of polyvinyl acetate phthalate with benzocaine: Isolation and characterization of 4-phthalimidobenzoic acid ethyl ester

Autor: Vijay Kumar, Gilbert S. Banker

Publikováno v: International Journal of Pharmaceutics. 79:61-65

The interaction of benzocaine with polyvinyl acetate phthalate in propylene glycol or a mixture of propylene glycol and ethyl alcohol was studied. The 4-phthalimidobenzoic acid ethyl ester, a major product that formed during storage, was isolated and
