Ojiji
Levulinic acid bụ ngwaahịa biomass, enwere ike iji ihe ndị sitere na ya, dị ka ethyl levulinate na alkyl levulinate, dị ka ihe mgbakwunye mmanụ.
A na-eji levulinic acid eme ihe maka calcium levulinate n'ọgwụ, dị ka esters na ihe mgbaze na ihe ndị na-eme ka plastik dị ọcha, nakwa maka ime valerolactone. Ka ojiji ya na-agbasa, o yikarịrị ka a ga-eji ihe mkpofu cellulosic mee ya. A na-enweta Mesitonic acid, otu homolog nke levulinic acid site na iji mesityl oxide na KCN.
Nmepụta hydrogen nke levulinic acid nwere ike imepụta kemịkalụ ndị ọzọ bara uru. Valeric-g-lactone, nke bụ ihe mgbaze dị irè nke nwere ọtụtụ ojiji, enwere ike inweta ya na nnukwu mkpụrụ. Enwere ike itinye hydrogen a na 1,4-pentandiol, nke mgbe mmiri gwụchara na-emepụta 1,3-pentadine (piperylene). A maara Piperylene ka ọ na-eme ka ọ bụrụ roba ma bụrụkwa isi iyi nke roba sịntetik (Ghorpade na Hanna 1997).
Levulinic acid bụ ihe na-ebute ụzọ maka njikọta nke ihe ndị bara uru dịka γ-valerolactone, ethyl levulinate, pentanoic acid na 2-methyl-tetrahydrofuran. Mmepụta na imepụta levulinic acid na-ebute ike biofuels.
Enwere ike iji ya na:
Nkwadebe nke ihe mejupụtara catalytic iji mepụta 5-hydroxymethylfurfural na furfural.
Nchịkọta nke isi ísì azụmahịa, fraistone.
Mmepụta nke pyrrolidone site na reductive amination.
Nchịkọta zuru oke nke mycobacterial arabinogalactan.
