Tikanga 1:
Ma te whakamahi i te 4-methyl-4-hydroxy-2-pentanone (te waipiro diacetone) hei taonga tauhohenga, he wai hei whakarewa, ka whakamahia te wairewa aqueous NaOBr mo te tauhohenga hauhau, ka whai i te waikawa me te tangohanga isobutanol. Ko te waikawa HMB i roto i te tangohanga isobutanol i tote tika ki te Ca (OH) 2 ki te whiwhi β - hydroxy - β - methylbutyrate calcium. Ko tenei tikanga nga painga o te parakore o te hua me te iti o te parahanga taiao.
- Tikanga 2:1) Te tauhohenga o te waikawa acetic glacial, waikawa sulfuric, me te H2O2, ka whai i te whakamaaramatanga korehau, ka puta he otinga o te waikawa peracetic;
- 2) Whakaranuhia te hua i puta mai i te taahiraa 1) ki te waipiro diacetone, taapirihia te methyl acetate hei whakarewa mo te tauhohenga, katahi ka whakamakuku ka kohia te hautanga 70 ℃. Ko te toenga i muri i te whakamakuku he otinga o te β - hydroxy - β - methylbutyric acid;
- 3) Tāpirihia te wai me te wairewa konutai waihā ki te toenga whakamakuku i whiwhi i te taahiraa 2) hei whakatika i te pH ki te 6.0-7.0. Whakawerahia te ranunga, ka tohua. Tāpirihia te konupūmā pūhaumāota ki te filtrate, whakakorikoria te tauhohenga, ka whakatika ano i te pH ki te 6.5-7.0 ki te whakaheke i te konupūmā β - hydroxy - β - methylbutyrate. Tātarihia ka whakamaroke kia whiwhi hua
