M'malo opanga mankhwala, Pali mitundu yosiyanasiyana yomwe imagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana. Mwa izi, Dimethyl Carbonate (Dmc), N-Methylacetamide (Nma), ndi adipic dihydrazide (ADH) imirirani malo awo apadera ndi mapulogalamu akuluakulu.
Dimethyl Carbonate (Dmc), N-Methylacetamide (Nma), ndi adipic dihydrazide (ADH) ndi mitundu itatu yodabwitsa ndi zinthu zosiyanasiyana komanso mitundu yosiyanasiyana. Kugwiritsa ntchito kwawo komanso kugwira ntchito kwawo kumapangitsa kuti zigawo zikhale zofunikira m'mafakitale ambiri, Kuchokera pakupanga mankhwala ndi mankhwala kwa ma plastics ndi nsalu.
Dimethyl Carbonate (Dmc): Zosungunulira komanso kubwereza
Dimethyl carbonate kuchokera China dimethyl carbonate othandizira, zodziwika bwino monga dmc, ndi gawo lolinganizidwa ndi njira ya mankhwala Ch3oco2ch3. Ndi wopanda mtundu, madzi oyaka ndi fungo labwino, Kupangitsa kuti kukhala wosungunulira komanso kubwereza m'makampani ambiri a mafakitale.
Kupanga: DMC imapangidwa makamaka chifukwa cha methanol ndi carbon monoxide pamaso pa chothandizira. Izi zimakhudza kubereka kwa methanol, chifukwa pakupanga kwa DMC.
Mapulogalamu:
Zosungunulira: DMC imagwiritsidwa ntchito kwambiri ngati zosungunulira m'mafakitale osiyanasiyana, kuphatikizapo zojambula, zokutira, ndi zomatira. Imagwiritsidwanso ntchito pochotsa zinthu zachilengedwe komanso ngati wothandizira.
Wogwilitsidwa: DMC imagwira ntchito ngati yofunika popanga polycarbonate, pulasitiki yogwira ntchito kwambiri yogwiritsidwa ntchito pazotsatira zingapo, kuphatikiza magawo autotive, Zida zamagetsi, ndi zida zamankhwala.
Zowonjezera mafuta: DMC imapeza ntchito ngati yowonjezera mafuta, Makamaka mu injini za dizilo, Komwe kumathandizira kuyaka kwamphamvu ndikuchepetsa mpweya.
N-Methylacetamide (Nma): Por aprotic solvent
N-methylartamide ndi China n-fithyelartamide wopanga, nthawi zambiri amatchedwa Nma, ndi gawo lolinganizidwa ndi mawonekedwe a mankhwala Chi3coch3. Ndi fungo lopanda utoto wokhala ndi fungo lofatsa ndipo limawerengedwa ngati porrutic yosungunulira.
Kupanga: NMA imapangidwa makamaka chifukwa cha zomwe acetic andhydride ndi methylamine. Njirayi imaphatikizapo kuyamwa kwa methylamine, chifukwa pakupanga nma.
Mapulogalamu:
Zosungunulira: NMA imagwiritsidwa ntchito kwambiri ngati zosungunulira m'mafakitale osiyanasiyana, kuphatikizapo mankhwala, zodzoladzola, ndi aburamu. Imagwiritsidwanso ntchito popanga inki ndi utoto.
Wogwilitsidwa: NMA imagwira ntchito ngati kaphatikizidwe ka zinthu zambiri zopangidwa ndi zopangidwa, kuphatikizapo mankhwala, mankhwala ophera tizilombo, ndi zonunkhira.
Funda: NMMA imapeza ntchito ngati pulasitiki, kukulitsa kusinthasintha ndi kukhazikika kwa mapulaneti.
Adipic Dihydrazide (ADH): Wapakatikati
Adwic diihdrazide ndi China adipic diihdrazide othandizira, ofupikitsidwa kwambiri ngati adh, ndi gawo lolinganizidwa ndi mankhwala a mankhwala a com(Nhnh2)2. Ndi yoyera, Crystalline cholimba ndi malo osungunuka 129-131 ° C.
Kupanga: Adh amapangidwa makamaka chifukwa cha zomwe adipric acid ndi hydrazine. Njirayi imaphatikizapo kukhazikika kwa adipic acid ndi hydrazine, chifukwa cha mapangidwe adh.
Mapulogalamu:
Wapakati: ADH imagwira ntchito ngati yapakatikati pakupanga ma poizoni osiyanasiyana, kuphatikizapo polyomides, ma poureurethanes, ndi polysisters.
Mtumiki wolumikizira: ADh amagwiritsidwa ntchito ngati wothandizira wolumikizirana popanga ma thermosetit, kulimbikitsa mphamvu zawo ndi kulimba.
Antioxidantant: ADh amapeza ntchito ngati antioxidant mu chakudya ndi mafakitale a mankhwala, Kuletsa kuwonongeka kwa zinthu chifukwa cha oxidation.
