ved<\/a> fremstilling af andre kemikalier, f.eks. methyl-2-pyrrolidon.<\/p>\nHvordan fremstilles GBL?<\/h4>\n
Der blev fundet ekstrakter af GBL fra uforfalskede vinpr\u00f8ver. Dette fund viser, at i nogle vine er GBL naturligt til stede og kan findes i lignende produkter. Detektionskoncentrationen var omkring 5 \u03bcg\/mL og blev let fulgt af en GC\/MS-analyse med en simpel fjernelsesteknik. I ostesmag findes GBL, men generelt er den endelige f\u00f8devare 0,0002% GBL. GBL.<\/p>\n
Dehydrogenering af 1,4-butandiol ved 180-300 \u00b0C, atmosf\u00e6risk tryk i n\u00e6rv\u00e6r af kobberkatalysator, producerer \u03b1-Butyrolactone industrielt.<\/p>\n
Denne proces vender tilbage. er omkring 95%. Udrensning finder sted ved at ekstrahere den flydende gasfase.<\/p>\n
Oxidationen af \u200b\u200btetrahydrofuran, s\u00e5som vandigt natrium\u00a0bromat a>, kan ogs\u00e5 opn\u00e5s i laboratoriet. GABA bruger Sandmeyer-reaktionen som en alternativ vej.<\/p>\n
Anvendelser af GBL:<\/h4>\n
De industrielle anvendelser af GBL er udbredt. En stor anvendelse af GBL er pyrolidoner, der er meget udbredt i industrielle kemikalier som et mellemprodukt i fremstillingen. GBL bruges ogs\u00e5 som en anden hovedkomponent i produkter som printpladerensere i elektronik, malingfjernere og neglelakfjernere p\u00e5 grund af deres h\u00f8je solvensegenskaber. Det bruges som opl\u00f8sningsmiddel af polyacrylonitril, celluloseacetat og polystyren. Produktion af herbicider og produktion af l\u00e6gemidler indg\u00e5r ogs\u00e5 i syntesen, f.eks. DL-methionin, piperidin, phenylsm\u00f8rsyre og thiosm\u00f8rsyre.<\/p>\n
GBL misbruges som en v\u00e6ske, der ofte fejlagtigt pr\u00e6senteres som GHB under ulovlig salg. En ml h\u00f8jrent GBL svarer cirka til 2,5 g GHB 49. Der er online kemiske leverand\u00f8rer, der s\u00e6lger GBL, der markedsf\u00f8rer GBL som reng\u00f8ringsopl\u00f8sningsmiddel, multifunktionsfjerner eller
\nkrompolish og som hjulrens.<\/p>\n
