Vanowanzo shandiswa kurongedza hupfu.Zvinoenderana nezvinodiwa nevatengi.Naizvozvo, tiudze zvaunoda usati warongedza kana uine zvakakosha zvikumbiro.
1kg kusvika 25kg Kurongedza kwekunze kwakaoma.Uye zvakaoma kucheka uye kukuvadza.Inogona kudzivirira zvigadzirwa zvako zvakakwana.
Ester inogadzirwa kubva kune esterization reaction ye inorganic acid kana organic acid kana doro.Doro kana phenol kana acidic anhydride, doro uye ethylene, yemahara acidic asidhi uye mafuta enitrogen zvinobva kune zvinogonawo kugadzira ester.Iyo hydrogen paalpha-carbon iri muester molecules inorasikirwa nemolecular alcohol neimwe molecular ester pasi pe alkaline mamiriro ekugadzira β-keto ester, iyo inonzi ester contraction reaction.Semuenzaniso, acetyl acetate inogadzirwa kugadzira acetyl ethyl acetate.Kuita uku kwakakosha zvakanyanya mune organic synthesis.
Zita re ester rinobva pazita rinoenderana re carboxylic acid uye doro kana phenol, se "imwe asidhi uye imwe ester".Circle esters inonzi lactone (lactone).Izvo zvemakemikari ester akafanana neamyl niche anhydride, iyo inowanzoita hydrolysis, doro uye ammonia reaction.Yakaderera-giredhi ester inonhuhwirira uye inoputika isina ruvara mvura, uye advanced ester yakasimba.Estes zvakakosha zvinonyungudutsa uye zvigadzirwa zvekugadzira, uye mamwe maester zvinodhaka pachazvo.Zvinoenderana nerudzi rweasidhi, ester inogona kukamurwa kuita inorganic acid ester uye organic acid ester.Etate, ethyl acetate ine mafuta ester, acetate inonhuhwirira ester, uye namanonate inonzi cyclic ester.
Iyo ester kazhinji imvura isina ruvara isina ruvara.Iyo ester inogadzirwa nerudzi rwemafuta uye doro rakazara rine kunhuhwirira kwemichero, iyo inogona kunyungudika mumvura, uye zvakare yakaoma kunyungudika mumvura.Imwe ester flash point yakaderera uye inowanzotsva.Iyo steam inogona kutorwa nekufema turakiti, uye iyo ester yemvura inogona kubatwa neganda.Mushure mekutora, inonyungudika mu plasma, uye mamwe acho anobudiswa kuburikidza nemapapu neitsvo.Mushure meimwe hydrolysis, shandura kuita yakajairika metabolic maitiro.Kuwedzera kune mashoma emakomponi eester, mazhinji acho ane muchetura uye ane muchetura zvakanyanya, uye mazhinji acho ane micro-chepfu kune yepakati chepfu zvikamu, uye mazhinji acho haana-chepfu.Kune makumi matatu nemasere esters mumapoka ekunhuhwirira kwetii.Zvikuru: ① mafuta ester: anogadzirwa nedoro uye mafuta, senge ethyl acetate, hexyl hexyate.② Inonhuhwirira ester: inogadzirwa nedoro uye inonhuhwirira asidhi, seShun-3-hexylzyl.③ Circin esters: inogadzirwa nedoro uye cyclocar, senge jasmone hyacxide.Iyo ester kazhinji haina kwayakarerekera, iyo inogona kuve hydrolyzed uye inoburitsa doro uye asidhi.Nhamba dzekabhoni shoma dzinowanzova zvinwiwa zvinonhuhwirira, uye nhamba dzekabhoni dzakakwirira imvura uye zvinyoro zvisinganyunguriki mumvura.
