Kodi Butenediol ndi 1,4-Butanediol ndi chiyani?

Butenediol ndi 1,4-Butanediolndi mankhwala awiri osiyana omwe amagwiritsidwa ntchito m'mafakitale, mankhwala, ndi kupanga. Ngakhale kuti ali ndi mayina ofanana ndi mapangidwe a maselo, magulu awiriwa ali ndi zosiyana zingapo zomwe zimawasiyanitsa wina ndi mzake.

Choyamba,Butenediol ndi 1,4-Butanediolali ndi ma formula osiyanasiyana. Butenediol ili ndi ndondomeko, C4H6O2, pamene 1,4-Butanediol ili ndi ndondomeko ya C4H10O2. Kusiyana kwa mamolekyu ndi mawonekedwe ake kumakhudza momwe thupi lawo limapangidwira komanso mankhwala, monga kusungunuka ndi kuwira, kusungunuka, ndi reactivity.

Chachiwiri,Butenediol ndi 1,4-Butanediolali ndi ntchito zosiyanasiyana. Butenediol imagwiritsidwa ntchito makamaka popanga polyester ndi polyurethane resins, zomatira, plasticizers, komanso monga zosungunulira za utoto ndi zokutira. Mosiyana ndi zimenezi, 1,4-Butanediol imagwiritsidwa ntchito ngati chakudya chopangira mankhwala angapo, kuphatikizapo gamma-butyrolactone (GBL), tetrahydrofuran (THF), ndi polyurethanes. Kuphatikiza apo, imagwiritsidwa ntchito popanga zida zamagalimoto, zamagetsi, zamankhwala, ndi zodzola.

Chachitatu,Butenediol ndi 1,4-Butanediolali ndi poizoni wosiyanasiyana komanso zoopsa zomwe zimagwirizanitsidwa ndi kugwiritsidwa ntchito kwawo. Butenediol imadziwika kuti ndi yonyansa pakhungu ndi maso ndipo imatha kuyambitsa kupsa mtima pakukoka mpweya. Kumbali ina, 1,4-Butanediol imatchulidwa kuti ikhoza kukhala carcinogen ndi mutagen ndipo imakhala ndi chiopsezo chakupha kwambiri kwa anthu ngati italowetsedwa kapena kulowetsedwa.

Pomaliza,Butenediol ndi 1,4-Butanediolkukhala ndi njira zosiyanasiyana zopangira. Kupanga kwa Butenediol kumaphatikizapo kuchitapo kanthu kwa maleic anhydride ndi mowa, monga ethylene glycol kapena propylene glycol. Kupanga kwa 1,4-Butanediol, kumbali ina, kumaphatikizapo hydrogenation ya succinic acid, yomwe imapezeka kuchokera ku anaerobic fermentation ya zinthu zongowonjezwdwa, monga chimanga wowuma kapena nzimbe.

Pomaliza,Butenediol ndi 1,4-Butanediolndi mitundu iwiri yosiyana ya mankhwala okhala ndi ma formula osiyanasiyana a mamolekyu, ntchito, kawopsedwe, zoopsa, ndi njira zopangira. Ngakhale amagawana zofananira, monga momwe amagwiritsidwira ntchito popanga ma polyurethanes, ali ndi zinthu zapadera zomwe zimawapangitsa kukhala oyenera ntchito zosiyanasiyana. Ndikofunika kumvetsetsa kusiyana kumeneku kuti kuwonetsetse kuti akugwiritsidwa ntchito motetezeka komanso moyenera m'mafakitale ndi ntchito zosiyanasiyana.
