I kēia mau lā iho nei, ua lilo ka 1,4-butanediol (BDO) i kumuhana wela ma ke kahua kemika. Ma ke ʻano he mea maka kemika organik koʻikoʻi, ke hoʻokomo nei ia i ka ikaika hou i loko o nā ʻoihana he nui me kāna mau noi ākea, e hoʻokele ana i ka hoʻomohala ikaika o kahi kaulahao ʻoihana ākea.
Ma nā laina hana o nā huahana polyester, hōʻike ka 1,4-butanediol i ka waiwai hiki ʻole ke hoʻololi ʻia. ʻO ka synthesis o ka polybutylene terephthalate (PBT) e hilinaʻi nui ʻia ma luna o ia mea. ʻO PBT, ma ke ʻano he plastic ʻenekinia polyester thermoplastic hana kiʻekiʻe, he mau waiwai mechanical koʻikoʻi, kūpaʻa ikaika i ka corrosion kemika, a me ka insulation uila maikaʻi loa a me ke kūpaʻa dimensional. I kēia manawa, ke ulu wikiwiki nei ka ʻoihana uila a me nā lako uila, me nā lako home akamai like ʻole a me nā mea uila pololei e puka mau ana. ʻO nā hale lako uila a me nā mea hoʻohui i hana ʻia me nā mea PBT ʻaʻole wale e hōʻoia i ka palekana a me ke kūpaʻa o nā lako akā hāʻawi pū i nā huahana me kahi hiʻohiʻona maikaʻi a paʻa, e alakaʻi ana i ka piʻi ʻana o ke koi mākeke. Hōʻike pū ka ʻoihana hana kaʻa i kahi makemake nui no PBT. Hiki i nā ʻāpana e like me nā lima puka kaʻa a me nā bumpers i hana ʻia me PBT ke kū i ka erosion o nā kūlana alanui paʻakikī me ka hoʻomaikaʻi ʻana i ke ʻano holoʻokoʻa o ke kaʻa.
Ma nā hale hana hana o ka polyurethane thermoplastic (TPU), ʻo 1,4-butanediol kekahi "lālā" koʻikoʻi. Hoʻohui ʻo TPU i ka elasticity kiʻekiʻe o ka rubber me ka maʻalahi o ka hana ʻana o ka plastic, a ʻo kāna mau huahana i hoʻopau ʻia he kūpaʻa i ke kapa, kūpaʻa i ka ʻaila, a kūpaʻa i ke anu. Mai nā kapuaʻi o nā kāmaʻa haʻuki i kēlā me kēia lā, e hāʻawi ana i ke kākoʻo ʻoluʻolu a lōʻihi no ka poʻe hoihoi i nā haʻuki, a hiki i nā paipu, nā ʻūpā uea a me nā kaula i nā hiʻohiʻona ʻoihana, e pale ana i ka palekana o ka hoʻoili ikehu a me ka lawe ʻana i nā mea, a laila i nā kāʻei conveyor ʻoihana e holo wikiwiki ana, e hōʻoiaʻiʻo ana i ka hana maʻalahi o ka laina hana, aia ʻo TPU ma nā wahi āpau, a ʻo ia ke kahua hana i kau ʻia e 1,4-butanediol e hiki ai.
Ua loli hou nā ʻoihana uhi, ʻīnika, a me ka paʻi ʻana a me ka hoʻoluʻu ʻana i nā mea hou i hala koke aku nei mahalo i ka 1,4-butanediol. ʻO ka γ-butyrolactone i hana ʻia mai ia mea he kiʻekiʻe ka paila a me ka solubility maikaʻi loa, hiki ke hoʻoheheʻe maʻalahi i nā hui organik a me nā polymers like ʻole, e hoʻolilo ana i nā kala o nā uhi i ʻoi aku ka like, ʻoi aku ka ikaika o ka hoʻopili ʻana o nā ʻīnika, a ʻoi aku ka maopopo a me ka ʻōlinolino o nā ʻano o ka paʻi ʻana a me ka hoʻoluʻu ʻana, e kōkua ana i ka hoʻomaikaʻi ʻana i ka ʻoihana kemika kuʻuna. Eia kekahi, ma ke ʻano he mea hoʻomaka no ka synthesis o nā mea ʻala a me nā mea waena lāʻau lapaʻau, ke wehe mālie nei ʻo γ-butyrolactone i kahi puka hou no ka noiʻi a me ka hoʻomohala ʻana i nā kemika maikaʻi, a manaʻo ʻia e hoʻoulu i nā huahana hou aʻe e hoʻokuʻu ʻia ma ka mākeke.
Ma lalo o ka nalu nui o ka ʻoihana pākahi lithium, ua huki nui ʻia ka manaʻo o N-methylpyrrolidone (NMP), kahi derivative o 1,4-butanediol. Ma ke ʻano he solvent aprotic polar, ua lanakila ʻo NMP i ka pilikia o ka solubility maikaʻi ʻole o nā mea electrode pākahi lithium, e hoʻomaʻamaʻa ana i ka hui like ʻana o nā mea hoʻopaʻa a me nā mea hana. ʻO ia ke koa kaulana ma hope o ka hoʻomaikaʻi ʻana i ka hana a me ka maikaʻi o nā pākahi lithium, e kākoʻo ikaika ana i ka mileage hou o nā ʻoihana e like me nā kaʻa ikehu hou a me nā mea mālama ikehu.
Ma nā palena o ke ʻano a me nā lole, ʻo ka tetrahydrofuran (THF) i hana ʻia me ka komo ʻana o 1,4-butanediol ua hoʻololi hou ʻia i polytetrahydrofuran (PTMEG), ka mea i lilo i mea maka no nā olonā spandex a me nā elastomers polyurethane. ʻO kēia ka mea e hoʻohālikelike ai i nā lole haʻuki a me nā lole kiʻekiʻe i nā piʻo o ke kino kanaka, e hoʻohui ana i ka ʻoluʻolu a me ke ʻano o ke ʻano, a hāʻawi i nā lole me ka elasticity kiʻekiʻe a me ka maʻalahi i manaʻo ʻole ʻia.
Ma ke kahua o ka noiʻi a me ka hoʻomohala ʻana i nā lāʻau lapaʻau, hana mālie ʻo 1,4-butanediol ma ke ʻano he "hero unsung". Ma ke ʻano he kikowaena lāʻau lapaʻau koʻikoʻi, komo ia i nā ʻanuʻu synthesis paʻakikī o kekahi mau lāʻau steroid a me nā antibiotics. Ua like ia me nā poloka hale palupalu no ke kūkulu ʻana i kahi hale molekala, e kōkua ana i nā mea noiʻi e kālai i nā ʻano lāʻau lapaʻau ʻoi aku ka maikaʻi a me ka hāʻawi ʻana i nā pōkā no ka lanakila ʻana i nā maʻi paʻakikī.
Me ka hoʻomaikaʻi mau ʻana o ka ʻenehana a me ka ʻimi hohonu ʻana i ke koi o ka mākeke, manaʻo ʻia e hoʻomau ka ʻoihana 1,4-butanediol i ka hoʻonui ʻia, me nā ʻoihana uka a me lalo e hui pū ana i ka hana hou a me ka puka ʻana mai i nā kahua e kū mai ana, e kākau ana i kahi mokuna hou i ka ʻoihana kemika.
