Nhanganyaya

(S) -3-hydroxy-γ-butyrolactone is an organic compound. Imvura isina ruvara ine kutapira, muchero.

Kune nzira dzakawanda dzekugadzirira kwe (S) -3-hydroxy-γ-butyrolactone, iyo inowanzowanikwa ne catalytic hydrogenation. Iyo chaiyo nzira ndeyekuita chiyero chakakodzera che γ-butyrolactone ine catalyst (yakadai semhangura-lead alloy) pane yakakodzera tembiricha uye kumanikidza, uye mushure mecatalytic hydrogenation, (S) -3-hydroxy-γ-butyrolactone inowanikwa.

Ruzivo Rwekuchengetedza: (S) -3-hydroxy-γ-butyrolactone ine huturu hwakaderera pasi pemamiriro ekushandisa zvakanyanya uye haisi kemikari ine ngozi. Kuchengetedza kunofanira kutorwa kudzivirira kubata neganda, maziso, uye nzira yekufema panguva yekushandiswa. Kana wasangana netsaona, sukurudza nemvura uye tsvaga kurapwa nenguva. Mushonga wacho unofanirwa kuchengetedzwa kure nekupisa uye tembiricha yakakwira, uye kudzivirira kusangana neoxidants uye acid. Mukuwedzera, inofanira kushandiswa maererano nemaitiro akakodzera ekushanda uye nzira dzakachengeteka dzekushanda.
