摘要:
New hemimercaptals of the formula ##STR1## in which X represents an oxygen or sulphur atom, a process for their preparation and their use as flavorings have been found.
摘要:
Dimethylfuryl-dihydro-1,3,5-dithiazines are useful flavorings having low taste threshold values. They impart a coffee or mocha taste, in particular to drinks, confectionery and bakery products.
摘要:
Unsymmetrical dihydrodithiazines of the formula ##STR1## in which one of the substituents R.sub.1 and R.sub.2 represent a C.sub.3 -C.sub.5 -alkyl group while the other is a methyl group and R.sub.3 represents a hydrogen atom, or R.sub.1 represents a methyl group and R.sub.2 and R.sub.3 together form a C.sub.3 -C.sub.4 -alkylene radical, a process for their preparation and their use as fragrances and flavorings.
摘要:
The invention relates to new thio-alkanones of the formula ##STR1## in which X represents an oxygen or sulphur atom,R.sub.1 represents hydrogen or a C.sub.1 -C.sub.2 -alkyl group and the broken lines represent a single bond or no bond,to a process for their preparation and their use as flavorings.
摘要:
Use of 3-acylthiohexyl esters of the formula ##STR1## wherein R.sup.1 and R.sup.2 independently of one another represent hydrogen, C.sub.1 -C.sub.6 -alkyl or C.sub.5 -C.sub.12 -aryl, including furyl and thienyl, as aroma and/or odoriferous substances, and aroma and odoriferous substance compositions containing these compounds.
摘要:
The invention relates to new furfurylthioalkanes of the formula ##STR1## wherein n can be zero or 1R represents the methyl or ethyl radical if n is 0, and represents hydrogen or the methyl radical if n is 1, andR' represents methyl or ethyl,a process for their preparation and their use as aroma substances.
摘要:
A pressure relief valve for packages in which the valve element comprises a liquid impregnated porous element covering outlet openings in the package, with the liquid layer in the porous element being torn open by package contents pressures in excess of a predetermined value to permit gas outflow from the package.
摘要:
A process for decaffeinating green coffee comprising treating green coffee with at least one acetal of the general formula ##STR1## wherein R.sup.1 is a hydrogen atom or a methyl group and R.sup.2 and R.sup.3 are each a methyl group or an ethyl group, as an organic solvent, and removing solvent residues by steaming the treated green coffee.
