Ngwa nke ACETYL ACETONE

1. Pentanedione, nke a makwaara dị ka acetylacetone, bụ etiti nke pyraclostrobin, azoxystrobin na rimsulfuron nke na-egbu ahịhịa.

2. Enwere ike iji ya dị ka ihe eji emepụta ihe na ihe ndị na-eme ka ihe dị ndụ dị n'ime ya, a pụkwara iji ya dị ka ihe mgbaze.

3. A na-eji ya eme ihe dịka ihe nyocha na ihe na-ewepụta aluminom na tungsten na molybdenum.

4. Acetylacetone bụ ihe dị n'etiti na mmepụta ihe ndị sitere n'okike, ọ na-emepụta amino-4,6-dimethylpyrimidine na guanidine, nke bụ ihe dị mkpa maka ọgwụ. Enwere ike iji ya dị ka ihe mgbaze maka cellulose acetate, ihe mgbakwunye maka mmanụ ụgbọala na mmanụ, ihe na-ekpo ọkụ maka agba na varnish, ihe na-egbu egbu, na ọgwụ ahụhụ. Enwere ike iji acetylacetone dị ka ihe na-akpali mgbawa mmanụ, hydrogenation na mmeghachi omume carbonylation, yana ihe na-eme ka oxidation dị ngwa maka oxygen. Enwere ike iji ya wepụ oxides metal na ihe siri ike na-agbawa agbawa ma na-agwọ polypropylene catalyst. Na mba Europe na America, a na-eji ihe karịrị 50% na ọgwụ mgbochi afọ ọsịsa na ihe mgbakwunye nri.

5. Na mgbakwunye na ihe ndị a na-ahụkarị nke mmanya na ketone, ọ na-egosipụtakwa agba ọbara ọbara gbara ọchịchịrị na ferric chloride ma na-emepụta chelates na ọtụtụ nnu ígwè. Site na acetic anhydride ma ọ bụ acetyl chloride na acetone condensation, ma ọ bụ site na mmeghachi omume nke acetone na ketene enwetara. A na-eji Chemicalbook dị ka ihe na-ewepụta ígwè iji kewaa ion trivalent na tetravalent, ihe na-akpọ nkụ agba na ink, ọgwụ nje, ọgwụ nje, fungicides, ihe mgbaze maka nnukwu polymers, ihe ndị na-eme ka ihe dị nro maka mkpebi nke thallium, iron, fluorine, na ihe ndị na-eme ka ihe dị ndụ dị n'etiti.

6. Ndị na-eme ka ígwè gbanwee. Nchọpụta agba nke ígwè na fluorine, na mkpebi nke thallium n'ihu carbon disulfide.

7. Ihe ngosi nke Fe(III) nke complexometric titration; eji ya eme mgbanwe nke otu guanidine (dịka Arg) na otu amino dị na protein.

8. A na-eji ya eme ihe dị ka ihe na-eme ka ígwè na-agbanwe agbanwe; a na-eji ya eme ihe maka ikpebi agba nke ígwè na fluorine, na ịchọpụta thallium n'ihu carbon disulfide.

9. Ihe ngosi maka titration nke iron (III). A na-eji ya emezi otu guanidine dị na protein na otu amino dị na protein.
