Hoʻokumu ʻia ka cellulose propionate i ka wā e hana ʻia ai ka cellulose me ka waikawa propionic. Hoʻokumu ʻia ka butyrate cellulose i ka wā e hana ʻia ai ka cellulose me ka waikawa butyric.

Hiki ke hana ʻia nā esters cellulose ma ka hana ʻana i ka cellulose me ka waiʻona. ʻO nā waiʻona maʻamau i hoʻohana ʻia no kēia kumu he methanol, ethanol, a me isopropanol. Hoʻopuka ka hopena i nā ʻano ester like ʻole, ma muli o ke ʻano o ka waiʻona i hoʻohana ʻia.

Hiki ke hana ʻia nā esters cellulose ma ka hana ʻana i ka cellulose me kahi mea esterifying, e like me ka glycerol a i ʻole ethylene glycol. Hoʻopuka kēia hopena i nā ʻano ester like ʻole, ma muli o ke ʻano o ka mea esterifying agent i hoʻohana ʻia.

Hiki ke hana ʻia nā esters cellulose ma ka hana ʻana i ka cellulose me kahi mea hana halogenating, e like me ka chlorine a i ʻole bromine. Hoʻopuka kēia hopena i nā ʻano ester like ʻole, ma muli o ke ʻano o ka mea hoʻohana halogenating.

Hiki ke hana ʻia nā esters cellulose ma ka hana ʻana i ka cellulose me kahi mea hoʻoheheʻe, e like me ka hydrogen peroxide. Hoʻopuka kēia hopena i nā ʻano ester like ʻole, e pili ana i ke ʻano o ka mea hoʻoneʻe i hoʻohana ʻia.

Hiki ke hana ʻia nā esters cellulose ma ka hana ʻana i ka cellulose me kahi mea hoʻohui, e like me ka ammonia a i ʻole ka amine. Hoʻopuka kēia hopena i nā ʻano esters like ʻole, ma muli o ke ʻano o ka mea hoʻohana aminating i hoʻohana ʻia.

Hiki ke hana ʻia nā esters cellulose ma ka hana ʻana i ka cellulose me kahi mea hoʻohaʻahaʻa, e like me ka sodium borohydride a i ʻole lithium alumini hydride. Hoʻopuka kēia hopena i nā ʻano esters like ʻole, ma muli o ke ʻano o ka mea hoʻemi hoʻemi i hoʻohana ʻia.

Hiki ke hana ʻia nā esters cellulose ma ka hana ʻana i ka cellulose me kahi mea hoʻohui kea, e like me ka dialdehyde a i ʻole ka diisocyanate. Hoʻopuka kēia hopena i nā ʻano ester like ʻole, ma muli o ke ʻano o ka mea hoʻohui cross-link i hoʻohana ʻia.

Hiki ke hana ʻia nā esters cellulose ma ka hana ʻana i ka cellulose me kahi mea hana polymerizing, e like me ka vinyl monomer a i ʻole polyester. Hoʻopuka kēia hopena i nā ʻano esters like ʻole, ma muli o ke ʻano o ka polymerizing agent i hoʻohana ʻia.

Hiki ke hana ʻia nā esters cellulose ma ka hana ʻana i ka cellulose me kahi mea hoʻōla, e like me ka epoxy a i ʻole polyurethane. Hoʻopuka kēia hopena i nā ʻano ester like ʻole, ma muli o ke ʻano o ka lāʻau lapaʻau i hoʻohana ʻia.

Hiki ke hana ʻia nā esters cellulose ma ka hoʻopili ʻana i ka cellulose me kahi mea palaki, e like me ka phthalate a i ʻole ka polyethylene glycol. Hoʻopuka kēia hopena i nā ʻano esters like ʻole, e pili ana i ke ʻano o ka mea hana plasticizing i hoʻohana ʻia.

Hiki ke hana ʻia nā esters cellulose ma ka hana ʻana i ka cellulose me kahi surfactant, e like me ka surfactant nonionic a i ʻole anionic. Hoʻopuka kēia hopena i nā ʻano ester like ʻole, ma muli o ke ʻano o ka surfactant i hoʻohana ʻia.

Hiki ke hana ʻia nā esters cellulose ma ka hana ʻana i ka cellulose me kahi mea pale ahi, e like me ka hydrocarbon halogenated a i ʻole ka pūhui phosphorous. Hoʻopuka kēia hopena i nā ʻano ester like ʻole, e pili ana i ke ʻano o ka pale ahi i hoʻohana ʻia.

I ka hopena, hana ʻia nā esters cellulose ma ka hana ʻana i ka cellulose me kahi waikawa, kahi waiʻona, kahi mea esterifying, kahi mea halogenating, kahi mea hoʻoheheʻe, kahi mea aminating, kahi mea hoʻohaʻahaʻa, kahi cross-linking agent, polymerizing agent, a curing agent. , he mea ho'opalekana, he surfactant, a i 'ole ka lapalapa ahi. ʻO ke ʻano o ka ester i hana ʻia ma muli o ke ʻano o ka reactant i hoʻohana ʻia. Hoʻohana ʻia nā esters cellulose i nā ʻano noi like ʻole, me ka uhi ʻana, nā adhesives, a me nā plastics.
