ʻO nā mea ʻulaʻula sulfurua ola ʻia ma mua o hoʻokahi haneli makahiki.Na Croissant a me Bretonniere mua i hana ʻia nā mea hoʻoheheʻe sulfur i ka makahiki 1873. Ua hoʻohana lākou i nā mea i loaʻa i nā fiber organik, e like me nā ʻāpana lāʻau, humus, bran, ʻōpala ʻōpala, a me nā pepa ʻōpala a me nā mea ʻē aʻe, i loaʻa ma ka hoʻomehana ʻana i ka alkali sulfide a me ka polysulfide alkali.ʻO kēia kala hygroscopic ʻeleʻele a ʻala ʻala he haku paʻa ʻole i ka ʻauʻau alkali a hiki ke hoʻoheheʻe ʻia i ka wai.Ke hoʻoluʻu ʻia ka pulupulu i loko o ka ʻauʻau alkali a me ka ʻauʻau sulfur, hiki ke loaʻa i nā wai ʻōmaʻomaʻo.Ke hōʻike ʻia i ka ea a i ʻole i hoʻoheheʻe ʻia me kahi hopena dichromate no ka hoʻoponopono kala, hiki ke ʻeleʻele ka lole pulupulu.No ka loaʻa ʻana o kēia mau mea waihoʻoluʻu maikaʻi loa a me nā kumukūʻai haʻahaʻa, hiki ke hoʻohana ʻia i ka ʻoihana pena pulupulu.
I ka makahiki 1893, hoʻoheheʻe ʻo R. Vikal i ka p-aminophenol me ka sodium sulfide a me ka sulfur e hana ai i nā mea ʻeleʻele sulfur.Ua ʻike pū ʻo ia ʻo ka eutectic o kekahi mau benzene a me naphthalene derivatives me ka sulfur a me ka sodium sulfide hiki ke hana i nā ʻano kala ʻeleʻele sulfur.Mai ia manawa, ua hoʻomohala ka poʻe i nā kala uliuli sulfur, nā kala ʻulaʻula Sulfur a me nā kala ʻōmaʻomaʻo sulfur ma kēia kumu.I ka manawa like, ua hoʻomaikaʻi maikaʻi ʻia ke ʻano hoʻomākaukau a me ka hana kala.Ua ʻike ʻia nā waihoʻoluʻu sulfur hiki ke hoʻoheheʻe ʻia i ka wai, nā wai sulfur wai a me nā wai sulfur pili i ke kaiapuni.
ʻO ka waihoʻoluʻu sulfur kekahi o nā mea pena i hoʻohana nui ʻia.Wahi a nā hōʻike, ʻo ka hoʻopuka ʻana o nā wai sulfur i ka honua a hiki i nā haneli kaukani mau tona, a ʻo ka ʻano mea nui loa he ʻeleʻele sulfur.ʻO ka hoʻopuka ʻana o ka ʻeleʻele sulfur ka helu no 75%-85% o ka huina o ka hoʻopuka ʻana o nā dyes sulfur.Ma muli o kāna synthesis maʻalahi, ke kumu kūʻai haʻahaʻa, ka wikiwiki maikaʻi, a me ka non-carcinogenicity, ua makemake ʻia e nā mea hana paʻi a me nā mea pena.Hoʻohana nui ʻia ia i ka pena ʻana i ka pulupulu a me nā mea cellulose ʻē aʻe, me ka ʻeleʻele a me ka polū ka mea i hoʻohana nui ʻia.
