9.Haka kuma za a iya hada methanol furotin, methanol a matsayin albarkatun kasa samar da microbial fermentation na methanol gina jiki da aka sani da na biyu ƙarni na guda-cell sunadaran, co.mpaja tare da sunadaran halitta, darajar abinci mai gina jiki ta fi girma, ɗanyen furotin ya fi na kifi kifi da wake wake, kuma yana da wadatar amino acid, ma'adanai da bitamin, waɗanda za a iya amfani da su a maimakon kifi, wake, wake, abincin kashi. , nama da garin nonon da aka yayyanka.
10.Methanol ana amfani dashi azaman tsaftacewa da kuma ragewa.
11.Yi amfani da matsayin nazari reagent, irin su kaushi, methylation reagents, chromatographic reagents. Har ila yau ana amfani da shi a cikin kwayoyin halitta.
12.Usually methanol ne mafi alhẽri ƙarfi fiye da ethanol, iya narke da yawa inorganic salts. Hakanan za'a iya haɗawa da man fetur a matsayin madadin man fetur. Ana amfani da methanol wajen samar da man fetur octane ƙari methyl tertiary butyl ether, methanol gasoline, methanol man fetur, da methanol protein da sauran kayayyakin.
13.Methanol ne ba kawai wani muhimmin sinadaran albarkatun kasa, amma kuma wani makamashi tushen da abin hawa man fetur da kyau kwarai yi. Methanol yana amsawa tare da isobutylene don samun MTBE (methyl tertiary butyl ether), wanda shine ƙarar gasoline mara gubar-octane kuma ana iya amfani dashi azaman sauran ƙarfi. Bugu da ƙari, ana iya amfani dashi don samar da olefins da propylene.
14.Methanol za a iya amfani dashi don samar da dimethyl ether. Sabon man fetur na ruwa da aka yi da methanol da dimethyl ether da aka tsara a wani kaso ana kiransa man fetur barasa ether. Ingancin konewar sa da ingancin yanayin zafi ya fi na iskar gas mai ƙarfi.
Bayanan Ajiye samfur:
1.Ajiye a cikin dakin ajiya mai sanyi, mai iska.
2.Kiyaye daga wuta da tushen zafi.
3.Kiyaye akwati a rufe.
4.Ya kamata a adana shi daban daga ruwa, ethanol, ether, benzene, ketones, kuma kada a taɓa haɗuwa.
5.Hana yin amfani da kayan aikin injiniya da kayan aiki masu sauƙi don haifar da tartsatsi.
Wurin ajiya ya kamata a sanye shi da kayan aikin jinya na gaggawa da kuma kayan matsuguni masu dacewa.
