Hoʻolauna

ʻO Phthalate (ʻike ʻia ʻo ortho-dimethoxybenzene, a i ʻole ODM no ka pōkole) he wai kala ʻole. ʻO kēia ka hoʻolauna ʻana i ke ʻano, hoʻohana, hana hana a me ka ʻike palekana o ODM:

Hiki ke hoʻoheheʻe ʻia i loko o nā ʻano mea hoʻoheheʻe organik.

 

Hoʻohana: Loaʻa i ka ODM kahi ākea o nā noi ma nā kahua he nui. Hiki ke hoʻohana ʻia no ka hana ʻana i nā kala, nā plastics, nā resins synthetic, a me nā mea ʻē aʻe.

 

Ke ala hoʻomākaukau: Hiki ke hoʻomākaukau ʻia ka ODM e ka hopena etherification phthalate. Ma lalo o ka hana a ka mea hoʻoheheʻe waika, hoʻopili ka phthalic acid me ka methanol e hana i ka methyl phthalate. A laila, hoʻopili ʻia ka methyl phthalate me ka methanol me kahi catalyst alkali e hana ai i ka ODM.

 

ʻIke palekana: Loaʻa i ka ODM kekahi mea ʻawaʻawa, a pono e mālama pono ʻia ka palekana i ka wā e hoʻohana ai a lawelawe ai iā ODM. He wai wela ia a pono e pale ʻia mai ka hoʻopili ʻana me nā kumu ahi. E pale pū i ka inhalation, pili me ka ʻili a me nā maka. I ka wā e hoʻohana ai i ka ODM, pono e lawe ʻia nā mea pale pilikino kūpono e like me ke komo ʻana i nā aniani pale a me nā mīkina lima, a me ka hōʻoia ʻana e hoʻohana ʻia ia i loko o kahi kaiapuni maikaʻi.
