Posachedwa, 1,4-qdiol (bdo) yakhala mutu wotentha m'munda wamankhwala. Monga mankhwala opangira mankhwala opangira zipatso, ndikuchotsa mphamvu zatsopano m'mafakitale ambiri omwe amagwiritsa ntchito mitundu yambiri, poyendetsa mwamphamvu za unyolo wa mafakitale.
Pa zopanga zopanga polyester, 1,4-finadiol zimawonetsa phindu losatha. Kaphatikizo wa polybutlene terephthalate (PBB) amadalira kwambiri. PBT, monga momwe ma ptroplastic polyester yolowera pulasitiki, imakhala ndi makina apamwamba, mphamvu yamphamvu yamankhwala oponderezedwa, komanso kusokonekera kosavuta. Pakadali pano, zamagetsi ndi zida zamagetsi zimakulitsa mwachangu, ndi zida zosiyanasiyana zanyumba zankhondo komanso zidole zamagetsi zomwe zimatuluka mosalekeza. Maukadaulo opanga magetsi ndi zolumikizira zopangidwa ndi zida za PBB samangotsimikizira chitetezo komanso kukhazikika kwa zida komanso mawonekedwe owoneka bwino komanso mawonekedwe oyambilira. Makampani opanga makina amawonetsanso zomwe amakonda kwambiri PBT. Zigawo monga chitseko chagalimoto ndi ma bupu opangidwa ndi pbt zimatha kupirira kukokoloka kwa misewu yovuta pokulitsa mawonekedwe agalimoto.
Mu zopangira zopanga za thermoplastic polyirethane (tpu), 1,4-RIENENIL ndi "membala" wamkulu ". TPU imaphatikiza kukongola kwa mphira ndi njira yosavuta ya pulasitiki, ndipo zinthu zake zomalizidwa ndizovala, zosagwirizana ndi mafuta, komanso zosagwirizana. Kuchokera ku nsapato zamasewera tsiku lililonse, zomwe zimapangitsa kuti zikhale bwino komanso zazitali zopitilira muyeso, kuperewera kwa ziphuphu, ndikutchinjiriza Izi zimapangitsa kuti zitheke.
Kukuta, inki, ndi kusindikiza ndi kupatsa mafakitale atsopano posachedwa zikomo kwa 1,4-finadienal. The γ-butterctone yopangidwa ndi ili ndi malo owiritsa komanso osinthika osungunuka mosavuta opanga ndi ma inling, ndikupanga zowoneka bwino komanso zowoneka bwino, zimathandizira kutsanzira kwa makampani achikhalidwe. Kuphatikiza apo, monga momwe zinthu zoyambira za synthesis zapakatikati, γ-butdylactone zimatseguka khomo latsopano pakufufuza ndi kukula kwa mankhwala abwino, ndipo akuyembekezeka kuti zinthu zina zatsopano ziyambike pamsika.
Pansi pa mafunde okwera a batiri a Lithiamu, N-Methylpyrolidrolid (NMM), wochokera ku 1,4-waniol, akopa chidwi. Monga poar aprotic solment, NMP yagonjetsa vuto la kusauka kwa osauka a batiri la chitoto cha lithum, kuwongolera yunifolomu kusakanikirana ndi zida zogwira ntchito. Ndi ngwazi yosagwirizana yomwe ikusintha kwa magwiridwe antchito ndi mtundu wa mabatire a Lifium, omwe amathandizira kwambiri mileage ya mafakitale monga zida zamagetsi zatsopano.
Pamidzi ya mafashoni ndi mapangidwe a tetrahydroforan (thf) zophatikizika ndi gawo la 1,4-qediol limasinthidwanso mu polytehhydroforan (ptmeg), ma pourestomer a Spandex. Izi zimapangitsa kuti zisuzi zizigwirizana ndi ma curve a thupi la munthu, kuphatikiza chitonthozo ndi mafakitale, komanso kutulutsa nsalu zomwe sizinapangidwe kale komanso kusinthasintha.
Mu gawo la kafukufuku wa mankhwala ndi chitukuko, 1,4-finadiool amachita mwakachetechete ngati "ngwazi yosavomerezeka". Monga gawo lofunikira la mlengalenga, limatenga nawo mbali mu kaphatikizidwe kovuta masitepe a mankhwala ena steroid ndi maantibayotiki. Zili ngati zonga zowoneka bwino zopangira nyumba yolekika, kuthandiza ofufuza kumatulutsa zida zamankhwala zothandiza komanso zopatsa mwayi wogonjetsa matenda ovuta.
Ndi kusintha mosalekeza kwaukadaulo ndi kufufuza kwakuya kwa msika wa 1,4-finediol kumayembekezedwa kuti apitilize, ndi mafakitale otsika kwambiri, akulemba mutu wawukulu wobwera, ndikulemba mutu wawukulu m'makampani opanga mankhwala.
