Kaihanga Utu Pai ACETYL ACETONE (2,4 PENTANEDIONE) CAS 123-54-6

whakaahuatanga poto:

Ko te ACETYL ACETONE, e mōhiotia ana ko te diacetylmethane, pentamethylene dione, he mea hanga mai i te acetone, ko te tātai ngota CH3COCH2COCH3, he wai mārama kore tae ki te kōwhai mārama. Ko te ACETYL ACETONE he ranunga o ngā tautomer e rua, te enol me te ketone, e noho ana i roto i te taurite hihiri. Ka hangaia e ngā isomers Enol Chemicalbook he hononga hauwai i roto i te ngota. I roto i te ranunga, ko te keto te 18%, ā, ko te alkenes te 82%. I whakamataohia te otinga petroleum ether o te ranunga ki te -78°C, ā, i whakapūpūhia te āhua enol hei totoka, kia wehea ai ngā mea e rua; i te hokinga o te āhua enol ki te pāmahana rūma, ka noho aunoa te ACETYL ACETONE ki te āhua taurite i runga ake nei.

Ngā Whakamahinga o te ACETYL ACETONE

1. Ko te Pentanedione, e mōhiotia ana ko te acetylacetone, ko te takawaenga o ngā patu harore pyraclostrobin, azoxystrobin me te patu taru rimsulfuron.

2. Ka taea te whakamahi hei rauemi mata me ngā takawaenga waro mō ngā rongoā, ā, ka taea hoki te whakamahi hei whakarewa.

3. Whakamahia hei matū tātari me te kaihoko tango o te konumohe i roto i te tungsten me te molybdenum.

4. He takawaenga te Acetylacetone i roto i te hanga rauropi, ā, ka hangaia he amino-4,6-dimethylpyrimidine me te guanidine, he rauemi mata rongoā nui. Ka taea te whakamahi hei whakarewa mō te cellulose acetate, hei tāpiri mō te penehīni me ngā hinu whakahinuhinu, hei whakamaroke mō te peita me te wanihi, hei patu harore, me te patu ngarara. Ka taea hoki te whakamahi i te Acetylacetone hei whakakorikori mō te pakaru hinu, te tauhohenga hauwai me te warowaihā, me te whakaterenga waikura mō te hāora. Ka taea te whakamahi hei tango i ngā waikura whakarewa i roto i ngā totoka porous me te rongoā i ngā whakakorikori polypropylene. I ngā whenua Pākehā me Amerika, neke atu i te 50% e whakamahia ana i roto i ngā rongoā ārai mate korere kararehe me ngā tāpiringa kai.

5. Haunga ngā āhuatanga noa o ngā waipiro me ngā ketone, he whero pouri hoki tōna tae me te ferric chloride, ā, ka hangaia he chelates me te maha o ngā tote whakarewa. Mā te acetic anhydride, te acetyl chloride rānei me te acetone condensation, mā te tauhohenga rānei o te acetone me te ketene i whiwhihia. Ka whakamahia te Chemicalbook hei tango whakarewa hei wehe i ngā ion trivalent me te tetravalent, ngā whakamaroke peita me te waituhi, ngā patu pepeke, ngā patu pepeke, ngā patu harore, ngā whakarewa mō ngā polymers teitei, ngā tauhohenga mō te whakatau i te thallium, te rino, te fluorine, me ngā takawaenga hanga waro.

6. Ngā matū whakarewa whakawhiti. Te whakatau i te rino me te wheowhio tae, me te whakatau i te thallium i te aroaro o te waro disulfide.

7. Tohu ine ira matatini Fe(III); e whakamahia ana mō te whakarerekētanga o ngā rōpū guanidine (pērā i a Arg) me ngā rōpū amino i roto i ngā pūmua.

8. Whakamahia hei kaihoko whakakōkī whakarewa whakawhiti; whakamahia mō te whakatau tae o te rino me te wheowhio, me te whakatau i te thallium i te aroaro o te waro disulfide.

9. He tohu mō te ine ine matatini rino (III). Whakamahia hei whakarerekē i ngā rōpū guanidine i roto i ngā pūmua me ngā rōpū amino i roto i ngā pūmua.
