ʻO 1,4-Butanediol glycidyl ether, i ʻike ʻia ʻo 1,4-butanediol dialkyl ether a i ʻole BDG, he mea hoʻohuihui. Hiki ke hoʻoheheʻe ʻia i ka hapa nui o nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol, methanol a me dimethylformamide. Hoʻohana ʻia ia ma ke ʻano he stabilizer no nā dyes a me nā puaʻa. Hiki ke hana ʻia e ka esterification o 1,4-butanediol me ka methanol a i ʻole ka hopena methanol. Hoʻokō ʻia nā kūlana hopena ma lalo o ke kaomi kiʻekiʻe a ma ke alo o kahi catalyst.

Ke hoʻohana nei i ka 1,4-butanediol glycidyl ether, pono e mālama ʻia e pale aku i ka pili ʻana me ka ʻili a me nā maka. I ka wā o ka hoʻohana ʻana a me ka mālama ʻana, pono e pale ʻia nā wela kiʻekiʻe a me nā kumu ahi. E makaʻala i ka hoʻopaʻa ʻana i nā pahu mālama e pale ai i ka evaporation a me ka leakage.
