Monoethanolamine (2-aminoethanol ethanolamine)
| Chilengedwe cha mankhwala | Ethanolamine ndi mtundu wa mowa wa amino womwe uli ndi viscous hygroscopic womwe uli ndi magulu a amine ndi mowa. Umafalikira kwambiri m'thupi ndipo ndi gawo la lecithin. Uli ndi mitundu yambiri ya ntchito zamafakitale. Mwachitsanzo, ungagwiritsidwe ntchito popanga mankhwala a zaulimi kuphatikizapo ammonia komanso kupanga mankhwala ndi sopo. Ungagwiritsidwenso ntchito ngati surfactant, fluorimetric reagent komanso ngati chochotsera CO2 ndi H2S. M'munda wamankhwala, ethanolamine imagwiritsidwa ntchito ngati chothandizira mitsempha yamagazi. Ulinso ndi mphamvu yoletsa histaminic, yomwe imachepetsa zizindikiro zoyipa zomwe zimayambitsidwa ndi kumangirira kwa H1-receptor. | |
| Mapulogalamu | Ethanolamine imagwiritsidwa ntchito ngati choyamwitsa kuti ichotse carbon dioxide ndi hydrogen sulfide kuchokera ku mpweya wachilengedwe ndi mpweya wina, ngati choyamwitsa khungu, komanso ngati choyamwitsa mankhwala a zaulimi. Ethanolamine imagwiritsidwanso ntchito mu zopukutira, njira zozungulira tsitsi, zosakaniza, komanso popanga zinthu zomwe zimagwira ntchito pamwamba (Beyer et al 1983; Mullins 1978; Windholz 1983). Ethanolamine imaloledwa m'zinthu zomwe zimagwiritsidwa ntchito popanga, kukonza, kapena kulongedza chakudya (CFR 1981). Ethanolamine imakumana ndi zotsatira zomwe zimachitika ngati ma amine oyambira komanso ma alcohols. Zotsatira ziwiri zofunika kwambiri za ethanolamine m'mafakitale zimaphatikizapo kuchitapo kanthu ndi carbon dioxide kapena hydrogen sulfide kuti ipange mchere wosungunuka m'madzi, komanso kuchitapo kanthu ndi ma acid amafuta atali kuti apange sopo wa ethanolamine wosalowerera (Mullins 1978). Ma ethanolamine omwe amalowetsedwa m'malo mwake, monga sopo, amagwiritsidwa ntchito kwambiri ngati ma emulsifiers, thickeners, wetting agents, ndi sopo mu zodzoladzola (kuphatikizapo zotsukira khungu, mafuta odzola, ndi mafuta odzola) (Beyer et al 1983). | |

| Nthawi yosungira zinthu | Malinga ndi zomwe takumana nazo, mankhwalawa akhoza kusungidwa kwa masiku 12.miyezi kuyambira tsiku loperekedwa ngati zasungidwa m'zidebe zotsekedwa bwino, zotetezedwa ku kuwala ndi kutentha ndikusungidwa kutentha pakati pa 5 -30°C. | |

Chitetezo
Mukamagwiritsa ntchito mankhwalawa, chonde tsatirani malangizo ndi chidziwitso chomwe chaperekedwa mu pepala la deta yachitetezo ndipo tsatirani njira zodzitetezera komanso zaukhondo kuntchito zoyenera pogwiritsira ntchito mankhwala.
Zindikirani
Deta yomwe ili m'buku lino imachokera ku chidziwitso chathu chamakono komanso zomwe takumana nazo. Poganizira zinthu zambiri zomwe zingakhudze kukonza ndi kugwiritsa ntchito malonda athu, deta iyi siimasula opanga kuti achite kafukufuku wawo ndi kuyesa; deta iyi sikutanthauza chitsimikizo chilichonse cha katundu wina, kapena kuyenerera kwa malondawo pacholinga china. Mafotokozedwe aliwonse, zojambula, zithunzi, deta, kuchuluka, kulemera, ndi zina zotero zomwe zaperekedwa pano zitha kusintha popanda chidziwitso cham'mbuyomu ndipo sizipanga mtundu wa malonda womwe wavomerezedwa. Ubwino wa malonda womwe wavomerezedwa umachokera kokha ku mawu omwe aperekedwa mu ndondomeko ya malonda. Ndi udindo wa wolandira malonda athu kuonetsetsa kuti ufulu uliwonse wa mwiniwake ndi malamulo ndi malamulo omwe alipo akutsatiridwa.
