Nigute ester ya selile ikorwa?
Ester ya selulose nicyiciro cyibikoresho bikozwe mugihe selile yatewe na aside cyangwa inzoga. Ibicuruzwa bivamo ni ibikoresho birwanya cyane amazi, ubushyuhe, n’imiti. Ester ya selile ikoreshwa muburyo butandukanye bwo gukoresha, harimo ibifuniko, ibifatika, na plastiki.
Est est selulose ikorwa mugukora selile hamwe na aside cyangwa inzoga. Ubusanzwe reaction ikorwa imbere ya catalizator, nka acide sulfurike, no mubushyuhe bwinshi. Igisubizo gitanga esteri zitandukanye zitandukanye, bitewe n'ubwoko bwa aside cyangwa inzoga zikoreshwa.
Esters ikunze kugaragara cyane ni selulose acetate, selulose propionate, na selile ya butyrate. Cellulose acetate ikorwa mugihe selile yatewe na acide acike. Cellulose propionate ikorwa mugihe selile yatewe na aside protionic. Cellulose butyrate ikorwa mugihe selile yatewe na acide butyric.
Est est selulose irashobora kandi kubyara mugukora selile hamwe n'inzoga. Inzoga zikunze gukoreshwa kuriyi ntego ni methanol, Ethanol, na isopropanol. Igisubizo gitanga ester zitandukanye zitandukanye, bitewe n'ubwoko bwa alcool ikoreshwa.
Esters ya selulose irashobora kandi kubyara mugukora selile hamwe na esterifying agent, nka glycerol cyangwa Ethylene glycol. Iyi reaction itanga esters zitandukanye zitandukanye, bitewe nubwoko bwa esterifying agent yakoreshejwe.
Esters ya selile irashobora kandi kubyara mugukora selile hamwe na halogene, nka chlorine cyangwa bromine. Iyi reaction itanga esters zitandukanye zitandukanye, bitewe nubwoko bwa halogenating agent yakoreshejwe.
Esters ya selile irashobora kandi kubyara mugukora selile hamwe na okiside, nka hydrogen peroxide. Iyi reaction itanga esters zitandukanye zitandukanye, bitewe n'ubwoko bwa okiside ikoreshwa.
Est est selulose irashobora kandi kubyara reaction ya selile hamwe na aminia, nka ammonia cyangwa amine. Iyi reaction itanga esters zitandukanye zitandukanye, bitewe nubwoko bwa aminating agent yakoreshejwe.
Esters ya selile irashobora kandi kubyazwa umusaruro mugukoresha selile igabanya ibintu nka sodium borohydride cyangwa lithium aluminium hydride. Iyi reaction itanga esters zitandukanye zitandukanye, bitewe n'ubwoko bwo kugabanya agent yakoreshejwe.
Esters ya selile irashobora kandi kubyara mugukora selile hamwe na agent ihuza, nka dialdehyde cyangwa diisocyanate. Iyi reaction itanga esters zitandukanye zitandukanye, bitewe n'ubwoko bwa cross-ihuza agent yakoreshejwe.
Esters ya selile irashobora kandi kubyara mugukora selile hamwe na polymerizing, nka vinyl monomer cyangwa polyester. Iyi reaction itanga esters zitandukanye zitandukanye, bitewe nubwoko bwa polymerizing agent yakoreshejwe.
Esters ya selile irashobora kandi kubyara mugukora selile hamwe numuti ukiza, nka epoxy cyangwa polyurethane. Iyi reaction itanga esters zitandukanye zitandukanye, bitewe nubwoko bwo gukiza bwakoreshejwe.
Esters ya selulose irashobora kandi kubyara mugukora selile hamwe na plasitike, nka phthalate cyangwa glycol polyethylene. Iyi reaction itanga esters zitandukanye zitandukanye, bitewe nubwoko bwa plasitike ikoreshwa.
Esters ya selile irashobora kandi kubyara mugukora selile hamwe na surfactant, nka nonionic cyangwa anionic surfactant. Iyi reaction itanga esters zitandukanye zitandukanye, bitewe n'ubwoko bwa surfactant yakoreshejwe.
Estereri ya selile irashobora kandi kubyara mugukora selile hamwe na retardant ya flame, nka hydrocarubone ya halogene cyangwa fosifori. Iyi reaction itanga esters zitandukanye zitandukanye, bitewe n'ubwoko bwa flame retardant yakoreshejwe.
Mu gusoza, esterose ya selile ikorwa mugukora selile hamwe na acide, inzoga, umukozi wa esterifike, agent wa halogenating, agent oxyde, agent aminating, agent igabanya, umukozi uhuza imipaka, umukozi wa polymerizing, umukozi ukiza , umukozi wa plastike, surfactant, cyangwa flame retardant. Ubwoko bwa ester bwakozwe biterwa nubwoko bwa reaction ikoreshwa. Ester ya selile ikoreshwa muburyo butandukanye bwo gukoresha, harimo ibifuniko, ibifatika, na plastiki.
