Phthalic Anhydride 99%, Kua rite mō te tuku~

Taupānga:

Tuatahi, he mea nui te mahi a te phthalic anhydride i roto i te ao hanga rongoā. He rauemi mata matua tēnei mō te hanga rongoā ārai-mumura, rongoā puku, rongoā paturopi, rongoā ārai-matepukupuku me ētahi atu rongoā. Hei tāpiri, he matū mua anō hoki te phthalic anhydride mō te hanga i ngā momo homoni tipu pērā i te homoni tipu me te auxin, he mea nui tēnei mō te whakatairanga i te tipu o ngā tipu me te whakanui ake i ngā hua o te hua.

Tuarua, he whānuitia te whakamahinga o te phthalic anhydride i roto i te umanga tae me te kakara. Hei takawaenga mō ngā tae me ngā mea kakara, ka whakamahia te phthalic anhydride ki te hanga mea kakara, ngā tae, ngā tae muka hangai, me ētahi atu. Nā ōna āhuatanga matū ahurei, kāore e taea te whakakapi i roto i ēnei mara, ka tāpirihia he tae me he kakara whai kiko ki te oranga o te tangata.

Hei tāpiritanga, he mea nui anō hoki te phthalic anhydride i roto i te hanga kirihou me te rapa. He rauemi mata nui tēnei mō te hanga i ngā matū polymer pēnei i te polyphenylene ether, te polyamide, me te polyimide. He tino pai ngā āhuatanga ā-tinana me te pumau matū o ēnei matū polymer, ā, he whānuitia te whakamahinga i roto i ngā motuka, ngā hikohiko, te hanga me ētahi atu mara, e tautoko ana i te whanaketanga o te hapori hou.

I roto i te mara o te hanga matū waro, he whānuitia ngā whakamahinga o te phthalic anhydride. Ka taea te whakamahi mō te carbonylation, te propylene oxidation, te whakarite i ngā esters waro whakahohe, te hydrogenation maroke, te aldehyde me te ketone esterification, te waikawa hauota me te alkaline oxidation. I roto i te hanga matū kore waro, ka taea te whakamahi i te phthalic anhydride hei hanga i ngā tote ammonium, ā, ka taea hoki te whakamahi hei kaihoko polymerization matua mō te hanga i te parahi konutea sulfide. Mā ēnei tauhohenga hanga ka whakaratohia he pūtake rauemi whai rawa mō te whanaketanga o te umanga matū.

Hei tāpiritanga, he nui hoki ngā whakamahinga o te phthalic anhydride i roto i te ao o ngā matū pai. Ka taea te whakamahi mō ngā momo wehewehe tioata me ngā tauhohenga whakaterenga, ā, ka taea hoki te whakamahi mō te hangarau whakarite me te horapa o ngā momo polymer konupūmā whanariki kore-ora. I roto i te tukatuka keri, ka taea te whakamahi i te phthalic anhydride mō te tukatuka kohuke o ngā putunga konganuku hei whakapai ake i te whai huatanga o te keri me te kounga o te konganuku. Hei tāpiritanga, ka taea hoki te whakamahi i te phthalic anhydride hei rauemi mata mō ngā patu pepeke me ngā patu pepeke, he mea nui ki te whakarite i te tipu o ngā hua me te whakapiki ake i ngā hua.

I roto i te hanga ahumahi, ko te phthalic anhydride te nuinga o te wā e whakamahia ana hei whakarewa me te tango. Nā te iti o te kohua me te nui o te wairewa, e whakamahia whānuitia ana te phthalic anhydride i roto i te whakamahine hinu me ngā ahumahi petrochemical hei rauemi mata pakaru. I taua wā anō, ka taea hoki te whakamahi hei matū tātari chromatographic me te tango mō ngā mea kakara, me ētahi atu, e whakarato ana i te huarahi whai hua mō te tātari matū me te tango mea kakara.

Hei tāpiritanga, ka taea hoki te whakamahi i te phthalic anhydride hei hanga vanillin, hei whakatau i te huka mimi, hei hanga i ngā momo synergists me te antifreeze, me ētahi atu. Ko tētahi hoki o ngā rauemi mata mō te hanga polyvinyl chloride stabilizers, ā, he kōwhiringa pai mō te maimoatanga mata whakarewa. I roto i te hanga rapa me te kirihou, ka taea te whakamahi i te phthalic anhydride hei tāpiri rapa me te tāpiri kirihou hei whakapai ake i te mahi me te kounga o te hua.
