Descriptio |
Furfuryl mercaptan ingratus odoris proprium habet. Praeparatur ex chloride chloride et furfurylo reagendo cum hydrolysi subsequenti reactionis productum; etiam per reductionem difurfurylorum in solutione alcoholica solvendo pulvere zinci utente et parvo acido acetico vel alumine reto utendo. Furfuryl mercaptan polymerize tendit in calefacta coram acidis mineralibus. |

|
Chemical Properties |
patet hyalina vel pallide lutea liquida |
|
Chemical Properties |
2-Furylmethanethiolum magni ponderis est aroma assa capulus. est liquor ingratus odoris, qui fit sicut capulus dilutum. |
|
usus |
Furfuryl Mercaptam est sapor volatilis componentis frumenti tortillae astulae. |
|
Praeparatio |
Furfuryl mercaptan praeparatur ex furfurylo alcohole, thiourea et hydrogenio chloride. Inde S-furfurylisothiouronium chloridi sodium adhaesit cum hydroxide ad furfurylum mercaptan. |
|
Aroma limina values |
Deprehensio: 0.005 ad 0.01 ppb; odoris notae ad 0.01%: cepae sulphuratae intensae ictum, lacrimator, leviter skunk sicut cum lacticiniis et satureia et notis coffeata. |
|
Gustus limina values |
Characteres saporis ad 0.2 ad 1 ppb: sulphureum, assatum, cepam, allium et capulus. |
|
salus Profile |
Venenum per viam intraperitonealem. Effectus generationis experimentalis. Adhibetur ut condimentum scelerisque, fructus, nuces et capulus. Cum calefacta compositione emittit toxici fumos SOx. Vide etiam MERCAPTANS. |
|
Synthesis chemica |
Praeparata chloridi chloridi reagit thiourea et furfuryli cum hydrolysi subsequenti reactionis producti; etiam per reductionem difurfuryl disulfde in solutione alcoholica utens zincum pulverem et parvam quantitatem acidi acetici vel alumina reducitur utens. |
