Li-cellulose esters li ka boela tsa hlahisoa ka ho arabela selulose ka joala. Litahi tse tloaelehileng tse sebelisoang molemong ona ke methanol, ethanol le isopropanol. Karabelo e hlahisa mefuta e fapaneng ea li-ester tse fapaneng, ho latela mofuta oa joala bo sebelisitsoeng.

Li-cellulose ester li ka boela tsa hlahisoa ka ho arabela selulose ka esterifying agent, e kang glycerol kapa ethylene glycol. Karabelo ena e hlahisa mefuta e fapaneng ea li-ester tse fapaneng, ho latela mofuta oa esterifying e sebelisitsoeng.

Li-cellulose ester li ka boela tsa hlahisoa ka ho arabela selulose ka halogenating agent, e kang chlorine kapa bromine. Karabelo ena e hlahisa li-ester tse fapaneng tse fapaneng, ho latela mofuta oa halogenating agent e sebelisitsoeng.

Li-cellulose ester li ka boela tsa hlahisoa ka ho arabela selulose ka motsoako oa oxidizing, joalo ka hydrogen peroxide. Karabelo ena e hlahisa mefuta e fapaneng ea li-ester tse fapaneng, ho latela mofuta oa oxidizing e sebelisitsoeng.

Li-cellulose ester li ka boela tsa hlahisoa ka ho arabela selulose ka ntho e nang le aminating, e kang ammonia kapa amine. Karabelo ena e hlahisa mefuta e fapaneng ea li-ester tse fapaneng, ho latela mofuta oa aminating e sebelisitsoeng.

Li-cellulose esters li ka boela tsa hlahisoa ka ho arabela selulose ka ntho e fokotsang, e kang sodium borohydride kapa lithium aluminium hydride. Karabelo ena e hlahisa mefuta e fapaneng ea li-ester tse fapaneng, ho latela mofuta oa sesebelisoa sa ho fokotsa se sebelisitsoeng.

Li-cellulose ester li ka boela tsa hlahisoa ka ho arabela selulose ka motsoako o kopanyang, joalo ka dialdehyde kapa diisocyanate. Karabelo ena e hlahisa mefuta e fapaneng ea li-ester tse fapaneng, ho latela mofuta oa li-cross-link tse sebelisitsoeng.

Li-cellulose esters li ka boela tsa hlahisoa ka ho arabela selulose ka moemeli oa polymerizing, joalo ka vinyl monomer kapa polyester. Karabelo ena e hlahisa li-ester tse fapaneng tse fapaneng, ho latela mofuta oa sesebelisoa sa polymerizing se sebelisitsoeng.

Li-cellulose ester li ka boela tsa hlahisoa ka ho arabela selulose ka moemeli oa phekolo, joalo ka epoxy kapa polyurethane. Karabelo ena e hlahisa mefuta e fapaneng ea li-ester tse fapaneng, ho latela mofuta oa moriana o sebelisoang.

Li-cellulose ester li ka boela tsa hlahisoa ka ho arabela selulose ka moemeli oa polasetiki, joalo ka phthalate kapa polyethylene glycol. Karabelo ena e hlahisa li-ester tse fapaneng tse fapaneng, ho latela mofuta oa sesebelisoa sa polasetiki se sebelisitsoeng.

Li-cellulose ester li ka boela tsa hlahisoa ka ho arabela selulose ka sehlahisoa se entsoeng ka holim'a metsi, se kang nonionic kapa anionic surfactant. Karabelo ena e hlahisa mefuta e fapaneng ea li-ester tse fapaneng, ho latela mofuta oa surfactant e sebelisitsoeng.

Li-cellulose ester li ka boela tsa hlahisoa ka ho arabela selulose ka ntho e thibelang lelakabe, joalo ka halogenated hydrocarbon kapa motsoako oa phosphorus. Karabelo ena e hlahisa mefuta e fapaneng ea li-ester tse fapaneng, ho latela mofuta oa lelakabe le sebelisoang.

Qetellong, li-cellulose esters li hlahisoa ka ho itšoara ka cellulose ka acid, joala, esterifying agent, halogenating agent, oxidizing agent, aminating agent, reduction agent, cross-linking agent, polymerizing agent, e phekolang. , ntho e etsang polasetiki, motho ea sebetsang ka holim'a metsi, kapa e thibelang lelakabe. Mofuta oa ester o hlahisoang o itšetlehile ka mofuta oa reactant e sebelisitsoeng. Li-cellulose ester li sebelisoa mefuteng e mengata e fapaneng ea ts'ebeliso, ho kenyeletsoa liphahlo, likhomaretsi le polasetiki.
