Ātiretine (C2H2)

Ngā tawhā hangarau

Āhitirena, ko te tātai ngota C2H2, e mōhiotia whānuitia ana ko te waro hau, ko te hau konupūmā kāpirati rānei, ko te mema iti rawa o ngā matū alkyne. Ko te Acetylene he hau kore tae, he paitini pakupaku, he tino mura hoki, he ngoikore ngā pānga whakangote me te ārai-waikura i raro i te pāmahana me te pēhanga noa. He iti te wairewa i roto i te wai, he wairewa i roto i te etanoru, te benzene, me te acetone. Kāore he kakara o te acetylene parakore, engari he kakara kāriki te acetylene ahumahi nā te mea kei roto ngā poke pēnei i te hauwai sulfide me te phosphine. Ko te acetylene parakore he hau mura kore tae, he kakara kakara. Ka pahū kaha pea i roto i te āhua wai me te āhua totoka, i roto rānei i te āhua hau me ētahi pēhanga. Ka taea e ngā āhuatanga pēnei i te wera, te wiri, me te mura hiko te whakaputa i te pahūtanga, nō reira kāore e taea te wairewa i raro i te pēhanga. Te rokiroki, te kawe rānei. I te 15°C me te 1.5MPa, he tino teitei te wairewa i roto i te acetone, me te wairewa o te 237g/L, nō reira ko te acetylene ahumahi he acetylene kua rewa i roto i te acetone, e kiia ana hoki ko te acetylene kua rewa. Nō reira, i roto i te umanga, i roto i ngā rango maitai kua whakakiia ki ngā rauemi pūwero pērā i te asbestos, ka pēhia te acetylene ki roto i te rauemi pūwero i muri i te mimiti i te acetone hei penapena me te kawe. Ka taea e te hau acetylene te whakaputa i te pāmahana teitei ina tahuna. Ka taea e te pāmahana o te mura oxyacetylene te eke ki te 3200℃. He maha te whakamahinga mō te tapahi whakarewa pērā i te hanga kaipuke me te hanganga maitai; e whakamahia ana mō te hanga rauropi (te hanga acetaldehyde, te waikawa acetic, te benzene, te rapa hangai, ngā muka hangai, me ētahi atu), rongoā hangai me ngā takawaenga matū vinyl acetylene, divinyl acetylene rānei; e whakamahia ana hei whakaputa hau paerewa pērā i te tātari hinu whakawhiti hau paerewa. Ka whakamahia te hau acetylene parakore teitei mō te mimiti ngota me ētahi atu taputapu. Ko te tikanga tākai o te acetylene ka rewa i roto i ngā whakarewa me ngā rauemi pūwero ka whakakīia ki roto i ngā rango maitai. Penapena ki roto i te whare putunga hauhautanga, hauhautanga. Puritia kia matara atu i te ahi me ngā pūtake wera. Kaua te pāmahana rokiroki e neke ake i te 30°C. Me penapena motuhake mai i ngā waikura, ngā waikawa, me ngā halogen, ā, karohia te rokiroki whakauru. Whakamahia ngā rama ātete-pahū me ngā whakaurunga hauhautanga. Kāore e whakaaetia te whakamahi i ngā taputapu miihini me ngā taputapu e ngāwari ana ki te mura. Me whai taputapu rongoā ohorere te wāhi rokiroki.

Taupānga:

①Te tapahi me te whakarewa i te konganuku:

Ka wera te acetylene, ka puta he pāmahana teitei. Ka eke te pāmahana o te mura oxyacetylene ki te 3200℃, e whakamahia ana mō te tapahi me te whakarewa i ngā konganuku.

②Ngā rauemi mata matū taketake:

Ko te acetylene te rauemi mata taketake mō te hanga o te acetaldehyde, te waikawa acetic, te benzene, te rapa hangai, me ngā muka hangai.

③ Whakamātautau

Ka taea te whakamahi i te acetylene tino parakore i roto i ētahi whakamātautau.
