Whakamahia hei whakakorikori, hei kaihonohono kapia, hei whakatere whakaora kapia; Hei tāpiri kapia, hei rapa; Whakamahia mō te tauhohenga hydroxylation, te tauhohenga hydrogenation, te tauhohenga isomerization, te hanga ketone iti-ngota koretake me te polymerization olefin waro iti me te copolymerization; Whakamahia hei whakarewa waro, whakamahia mō te cellulose acetate, te waituhi, te tae; Hei whakamaroke peita; Ngā rauemi mata mō te whakarite i ngā patu pepeke me ngā patu harore, ngā rongoā ārai mate korere kararehe me ngā tāpiringa kai; Karāhe whakaata infrared, kiriata kawe mārama (tote indium), kiriata kawe nui (tote indium) hei kaihanga; He tae motuhake te matatini konganuku Acetylacetone (kakariki tote parahi, whero tote rino, papura tote chromium) ā, kāore e wairewa i roto i te wai; Whakamahia hei rauemi mata mō te rongoā; Ngā rauemi hanga waro.
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.
