Ingoa pūhui o te hydroxyethyl cellulose

Ko te ingoa pūhui o Hydroxyethyl Cellulose (HEC) e whakaata ana i tana hanganga matū me nga whakarereketanga i mahia ki te cellulose taiao.Ko te HEC he cellulose ether, te tikanga i ahu mai i te cellulose na roto i te tukanga matū e kiia nei ko te etherification.Inaa, ka whakauruhia nga roopu hydroxyethyl ki te tuara cellulose.

Ko te ingoa IUPAC (International Union of Pure and Applied Chemistry) mo Hydroxyethyl Cellulose ka ahu mai i te hanganga o te cellulose me nga roopu hydroxyethyl kua taapirihia.Ko te hanganga matū o te cellulose he polysaccharide matatini i tito mai i nga waeine huka tukurua.

Ko te hanganga matū o Hydroxyethyl Cellulose ka taea te tohu hei:

I tenei whakaaturanga:

• Ko te waeine [-O-CH2-CH2-O-] e tohu ana i te tuara cellulose.
• Ko nga roopu [-CH2-CH2-OH] e tohu ana i nga roopu hydroxyethyl i whakaurua mai na roto i te etherification.

I runga i te uaua o te hanganga cellulose me nga waahi motuhake o te hydroxyethylation, he uaua te tuku ingoa IUPAC mo te HEC.He maha nga wa e pa ana te ingoa ki te whakarereketanga ki te cellulose, kaua ki te ingoa IUPAC motuhake.

Ko te ingoa e whakamahia nuitia ana ko “Hydroxyethyl Cellulose” e whakaatu ana i te puna (cellulose) me te whakarereketanga (nga roopu hydroxyethyl) i runga i te marama me te whakamarama.
