Ingoa matū o te hydroxyethyl cellulose

Ko te ingoa matū o te Hydroxyethyl Cellulose (HEC) e whakaata ana i tōna hanganga matū me ngā whakarerekētanga i mahia ki te cellulose tūturu. Ko te HEC he cellulose ether, ko te tikanga i ahu mai i te cellulose mā te tukanga matū e mōhiotia ana ko te etherification. Ina koa, ka whakauruhia ngā rōpū hydroxyethyl ki te tuara o te cellulose.

Ko te ingoa IUPAC (International Union of Pure and Applied Chemistry) mō te Hydroxyethyl Cellulose ka ahu mai i te hanganga o te cellulose me ngā rōpū hydroxyethyl kua tāpirihia. Ko te hanganga matū o te cellulose he polysaccharide matatini e titoa ana i ngā waeine huka auau.

Ka taea te whakaatu i te hanganga matū o te Hydroxyethyl Cellulose penei:

I roto i tēnei whakaaturanga:

• Ko te wae [-O-CH2-CH2-O-] te tuara o te cellulose.
• Ko ngā rōpū [-CH2-CH2-OH] e tohu ana i ngā rōpū hydroxyethyl i whakaurua mai mā te etherification.

I runga i te uaua o te hanganga o te cellulose me ngā wāhi motuhake o te hydroxyethylation, he uaua pea te whakarato i tētahi ingoa IUPAC pūnaha mō te HEC. He maha ngā wā ka pā te ingoa ki te whakarerekētanga i mahia ki te cellulose, kaua ki tētahi ingoa IUPAC motuhake.

Ko te ingoa e whakamahia whānuitia ana ko "Hydroxyethyl Cellulose" e whakaata ana i te pūtake (cellulose) me te whakarerekētanga (ngā rōpū hydroxyethyl) i roto i te huarahi mārama, whakaahua hoki.
