modum productio

Praeparatio ofisobutyric in butyric acidum acidum est similis, qui fit per spiritus, et isobutyraldehyde isobutyl thedirect oxidatio. Isobutyric acidcan generatae non directe ab aere per oxidatio isobutyraldehyde oroxygen. Alii modi sunt faciens acidum isobutyronitrile hydrolysis andmethacrylic hydrogenation. I-II-oxidatio de yl nitropropane prepareisobutyric acidum est etiam valorem altiorem cede. Purificatio ofIsobutyric azeotropic acidum potest reduci per destillationem in aqua andanhydrous isobutyric acidum potest distillari fromcarbon tetrachloride extrahendum est adeptus. Formic acid possunt agere Pascha, et Propylene L ° C in acidum est withthe catalysis de hydrofluoric isobutyrate et generate yl propylisobutyrate.
Application: Isobutyric butyric acidum acidum est non magis quam, est usus, sed similis hasthe butyric acidum, n. Acidum esters Isobutyric maxime usus toproduce sunt correspondentes, et sic quasi yl isobutyrate apricotincense, propyl isobutyrate cum pineapple saporem, saporem isobutyl isobutyrate withbanana, octyl isobutyrate uvis gustum, odor withjasmine isobutyrate benzyl, etc. Potest enim esse et parat flavors menstrua andalso exercendis armorum officinis usus est in varnishes et plasticizers. Isobutyric acidhas quaedam derivativa illius magna in industria, est productio ex isobutyronitrile forthe usi sunt media, et tunc dose toisobutylamidine conversis et rudis materiae, qui est de pesticidediazinon.
