tsimikizani kusintha
1. Thanzitsani cellon yapamwamba ya alkali yothetsera bwino pa 35-40 ℃ kwa theka la ola limodzi, ndikukhala zaka zapakati pa polymerization wa alkali Ikani fiberi ya alkali mu ketulo yoyeserera, onjezani ma proreyne oxide ndi methyl chloride nthawi ya 50-80 - kukakamizidwa kwakukulu ndi 1.8mpo. Kenako onjezani kuchuluka kwa hydrochloric acid ndi oxalic acid ndi madzi otentha pa 90 ° C kuti atsuke nkhaniyo kuti achuluke voliyumu. Madzi opanda madzi. Sambani mpaka kusalowerera, pomwe madzi ali ndi 60%, amawuma ndi mpweya wotentha pa 130 ° C mpaka 5%.
Njira Zoyeserera
Dzina la Njira: HyPromelsel - kutsimikiza kwa ma hydroxyprophocoxyl magulu - kutsimikiza kwa Hydroxypropoxyl Magulu

Tengani 0,5 g wa sungunuka wosungunuka, kuwonjezera 5 ml ya madzi ndikusakaniza bwino mu 100 ml ya madzi otentha, akusudzulidwa, Pitilizani kuwira kwa mphindi ziwiri, zilekeni ntchentche. Njira iyi iyenera kugwiritsidwa ntchito mu dongosolo latsopano.
ZOCHITIRA: Tengani 0,1 g ya izi, amayesa bwino, ikani mu distiction flask d, ndikuwonjezera 10 ml (g / g) Trichlorium trichloride. Ikani madzi mumpendenga wopaka b mpaka lolumikizana, ndikulumikiza chipangizo cha distillation. Abisirani Bwino B ndi D mu kusamba kwamafuta (kumatha kukhala glycerin), onetsetsani madzi osateketseko ndi madzi ozizira, ndipo ngati kuli kotentha kwake ndikuwongolera kukwera kwake. Kusamba kwamafuta kunathamangitsidwa kwa 155 ° C mkati mwa mphindi 30, ndipo kutentha kunasungidwa mpaka 50 ml ya distillate. Wogonjerayo adachotsedwa pachidutswachi, chophika ndi madzi, kutsukidwa ndi kuphatikiza njira yolumikizirana, ndipo madontho atatu a phenolphthalein yankho adawonjezeredwa. Timalani ku mtengo wamtundu wa 6.9-7.1 Chizindikiro Chosasintha, Chabati mpaka kumapeto ndi sodium thiosulfate njira yankho (0.02Mol / l), ndikujambulitsa voliyumu ya D2 (ml). Mayeso ena opanda kanthu adachitidwa, ndipo mavoliyumu va ndi vb (ml) ya kuwonongedwa sodium la phosuums hydroxide (0.02Mol / l) ndi sodium / l) adalemba motero. Kuwerengetsa hydroxyprovopoxy.
Chidziwitso: "Kuyenerera koyenera" kumatanthauza kuti zolemerazi ziyenera kukhala zolondola kwa chikwi chimodzi cha kulemera.
Kuchita Chitetezo
ngozi zaumoyo
Izi ndi zotetezeka komanso zopanda poizoni, zitha kugwiritsidwa ntchito ngati chowonjezera cha chakudya, alibe kutentha, ndipo sakukhumudwitsa khungu ndi mucous nembanemba. Nthawi zambiri amatengedwa kuti ndi otetezeka (FDA1985), kudya tsiku lililonse ndi 25mg / kg (fao / ndani 1985), ndi zida zodzitetezera ziyenera kuvala ntchito.
mphamvu ya chilengedwe
Pewani kufalitsa mwachisawawa kuti fumbi kuwuluka ndikuyambitsa kuipitsidwa kwa mpweya.
Zowopsa zakuthupi ndi zamankhwala: Pewani kulumikizana ndi magwero amoto, ndikupewa mapangidwe a fumbi lalikulu m'malo otsekedwa kuti mupewe ngozi zophulika.
Kuyendetsa ndi Kusunga Nkhani
Samalani ndi dzuwa, mvula, kunyozedwa, pewani dzuwa mwachindunji, ndikusunga pamalo owuma.
