Muaj ntau ntau txoj kev hluavtaws ntawm 10-hydroxy-2-decenoic acid, thiab cov hauv qab no yog ib txoj hauv kev ua hluavtaws:
(1) Hydroxymethylation ntawm isopropyl acetate: isopropyl acetate yog rhuab nrog methanol thiab sodium hydroxide nyob rau hauv lub reactor kom tau ib tug sib tov ntawm methyl acetate thiab isopropyl acetate. Tom qab ntawd cov sib tov tau tshwm sim nrog sodium hydroxide nyob rau hauv qhov kub thiab txias kom tau txais lub precursor ntawm 10-hydroxy-2-decenoic acid, 10-methoxy-2-decenoic acid methyl ester.
(2).Hydrogenation ntawm 10-methoxy-2-decenoic acid methyl ester: 10-methoxy-2-decenoic acid methyl ester yog rhuab thiab reacted nrog hydrogen thiab catalyst (xws li platinum catalyst ) nyob rau hauv lub reactor kom tau txais 10-hydroxy-2-decanoic acid methyl ester.
(3).Hydroxylation cov tshuaj tiv thaiv: 10-hydroxy-2-decenoic acid methyl ester yog reacted nrog iodine thiab sodium hydroxide nyob rau hauv lub reactor kom tau txais 10-hydroxy-2-decenoic acid.
(4).Esterification cov tshuaj tiv thaiv: 10-hydroxy-2-decenoic acid yog reacted nrog activator (xws li dimethyldichlorosilane) thiab acylation reagent (xws li propionyl chloride) nyob rau hauv lub reactor kom tau cov khoom esterification ntawm {{3 }}hydroxy-2-decenoic acid, xws li 10-hydroxy-2-decenoic acid propyl ester.
Txhawm rau ua tiav, txoj kev sib txuas ntawm 10-hydroxy-2-decenoic acid suav nrog hydroxymethylation ntawm isopropyl acetate, hydrogenation, hydroxylation thiab esterification ntawm 10-methoxy-2-decenoic acid methyl ester.
Raws li rau cov teb chaws uas nquag siv thiab cov khoom xa tawm txhua xyoo ntawm 10-hydroxy-2-decenoic acid, cov ntaub ntawv yuav txawv vim qhov sib txawv ntawm kev tsim khoom thiab kev xav tau ntawm ntau lub teb chaws thiab cheeb tsam. Nov yog qee cov ntaub ntawv tuaj yeem siv tau:
(1) Tuam Tshoj: Tuam Tshoj yog ib tug ntawm cov loj producers ntawm 10-hydroxy-2-decenoic acid nyob rau hauv lub ntiaj teb no. Raws li cov ntaub ntawv ntawm Tuam Tshoj Customs, Tuam Tshoj tus export ntim ntawm 10-hydroxy-2-decenoic acid nyob rau hauv 2019 yog 121 tons.
(2) Tebchaws Meskas: Tebchaws Meskas kuj yog ib tus neeg tsim khoom ntawm 10-hydroxy-2-decenoic acid. Raws li cov ntaub ntawv ntawm Teb Chaws Asmeskas Kev lis kev cai, cov khoom xa tawm ntawm 10-hydroxy-2-decenoic acid los ntawm Tebchaws Meskas xyoo 2019 yog 21 tons.
(3) Teb chaws Europe: Teb chaws Europe kuj yog ib qho ntawm cov chaw tsim khoom tseem ceeb thiab kev siv ntawm 10-hydroxy-2-decenoic acid. Txawm li cas los xij, cov ntaub ntawv ntawm Tebchaws Europe feem ntau yog cov txheeb cais ntawm tag nrho EU. Raws li EU cov ntaub ntawv, kev xa tawm ntim ntawm 10-hydroxy-2-decenoic acid hauv 2019 yog 128 tons.
Nws yuav tsum raug sau tseg tias cov ntaub ntawv no tsuas yog siv rau kev siv xwb, thiab cov ntaub ntawv tiag tiag yuav txawv. Tsis tas li ntawd, vim tias daim ntawv thov kev thov ntawm 10-hydroxy-2-decenoic acid yog txawv nyob rau hauv ntau lub teb chaws thiab cheeb tsam, qhov kev hloov ntawm export ntim tej zaum yuav cuam tshuam los ntawm ntau yam, nrog rau cov kev xav tau ntawm kev ua lag luam, nqi ntau lawm, thiab lwm yam.
