Sodium carboxymethyl cellulose solubility na mmiri

Okwu mmalite

Carboxymethyl cellulose (CMC) bụ ụdị mmepụta cellulose nke a na-ejikarị eme ihe na ụlọ ọrụ dị iche iche, gụnyere nri, ọgwụ, akwụkwọ, na textiles.Ọ bụ polymer soluble mmiri nke a na-emepụta site na mmeghachi omume cellulose na sodium monochloroacetate ma ọ bụ sodium dichloroacetate n'ihu alkali.CMC bụ ọcha, enweghị isi, ntụ ntụ na-enweghị ụtọ nke a na-eji dị ka ihe na-eme ka ọ sie ike, stabilizer, emulsifier, na onye na-akwụsịtụ na ngwaahịa dị iche iche.A na-ejikwa ya dị ka ihe nkedo na mbadamba nkume na capsules, yana dị ka mmanu na-emepụta mbadamba nkume.

Mbelata nke CMC n'ime mmiri dabere n'ọtụtụ ihe, gụnyere ogo nnọchi (DS), ịdị arọ molecular, na pH.Ogo nke nnọchi bụ ọnụọgụ nke otu carboxymethyl kwa otu anhydroglucose (AGU) na yinye polymer, a na-egosipụtakarị ya dị ka pasentị.Nke dị elu nke DS, ka CMC na-esiwanye ike ma na-agbaze ya na mmiri.The molekụla arọ nke CMC na-emetụtakwa ya solubility na mmiri;arọ molekụla dị elu na-abụkarị soluble karịa.N'ikpeazụ, pH nke ngwọta nwekwara ike imetụta solubility nke CMC;ụkpụrụ pH dị elu na-ebuli solubility nke CMC.

Solubility nke CMC na mmiri na-emetụtakwa ọnụnọ nke ihe ndị ọzọ na ngwọta.Dịka ọmụmaatụ, ọnụnọ nke electrolytes dị ka sodium chloride nwere ike ibelata solubility nke CMC na mmiri.N'otu aka ahụ, ọnụnọ nke organic solvents dị ka ethanol nwekwara ike ibelata solubility nke CMC na mmiri.

Enwere ike ikpebi ịdị nro nke CMC na mmiri site na ịlele ntinye nke CMC na ngwọta site na iji spectrophotometer.Enwere ike ikpebi ntinye nke CMC na ngwọta site na ịlele ntinye nke ngwọta na ogologo nke 260 nm.Ihe ntinye aka na ntinye nke CMC na ngwọta.

N'ozuzu, CMC na-agbaze na mmiri.Solubility nke CMC n'ime mmiri na-abawanye na ogo ngbanwe, ịdị arọ molecular, na pH.Solubility nke CMC na mmiri na-emetụtakwa ọnụnọ nke ihe ndị ọzọ na ngwọta.

Mmechi

Carboxymethyl cellulose (CMC) bụ polymer soluble mmiri nke a na-ejikarị na ụlọ ọrụ dị iche iche.Solubility nke CMC na mmiri na-adabere n'ọtụtụ ihe, gụnyere ogo nke nnọchi, ịdị arọ molecular, na pH.N'ozuzu, CMC dị nnọọ soluble na mmiri, na solubility ya na-abawanye na-abawanye ogo nke nnọchi, molecular arọ, na pH.Solubility nke CMC na mmiri na-emetụtakwa ọnụnọ nke ihe ndị ọzọ na ngwọta.Enwere ike ikpebi ntinye nke CMC na ngwọta site na ịlele ntinye nke ngwọta na ogologo nke 260 nm.
