1. Hoʻohana nui ʻia ka Hydroquinone ma ke ʻano he mea hoʻomohala kiʻi. Hoʻohana nui ʻia ʻo Hydroquinone a me kāna mau alkylates e like me ka polymer inhibitors i ke kaʻina o ka mālama monomer a me ka lawe ʻana. ʻO ka manaʻo maʻamau ma kahi o 200ppm.
2. Hiki ke hoʻohana ʻia e like me ka lāʻau a me ka ʻaila antioxidant, etc.
3. Ma ke kahua o ka mālama ʻana, hoʻohui ʻia ka hydroquinone i ka wai wela a me ka hoʻomaha
ka wai o ka ʻōnaehana hoʻomehana kaapuni i pani ʻia, hiki ke pale i ka ʻino o ka metala ma ka ʻaoʻao wai. ʻO ka Hydroquinone me ka umu wai deaerating agent, i loko o ka paila wai preheating deaeration e hoʻohui ʻia i ka hydroquinone, i mea e wehe ai i ke koena o ka oxygen dissolved.
4. Hiki ke ho'ohana 'ia no ka hana 'ana i ka anthraquinone dyes, azo, pharmaceutical raw material.
5. Hiki ke hoʻohana ʻia e like me ka mea hoʻopaʻapaʻa corrosion detergent, stabilizer a me antioxidant, akā hoʻohana pū ʻia i ka lauoho lauoho hoʻonaninani.
6.Photometric ka hoʻoholoʻana o ka phosphorus, magnesium, niobium, copper, silicon a me arsenic. Polarographic a me ka hoʻoholo volumetric o iridium. Nā mea ho'ēmi no nā waikawa heteropoly, nā mea ho'ēmi no ke keleawe a me ke gula.
