Abstract: PROBLEM TO BE SOLVED: To obtain a new compound useful as a medicine, a cosmetic, a food additive, a biological antioxidant and a stabilizer. SOLUTION: This compound is represented by formula I [R is a 1-12C hydrocarbon, a (substituted)cycloalkyl, a heterocyclic ring, etc.; R is an 8-30C hydrocarbon, a (substituted)alkyl, etc.; R is PO3 H2 or glycosidyl; R , R and R are each H, an alkyl, an aryl, an aralkyl, etc.; R is H, or CO-R (R is H, a 1-20C aliphatic or phenylvinyl)]. The compound represented by formula I is obtained by reacting a 5-halogenomethyl-chroman represented by formula II (X is Br or Cl) with an alkali(ne earth) metallic salt of ascorbic acid or an ascorbic acid derivative represented by formula III. The compound represented by formula I can be used to thereby stabilize an organic substance, especially a food, medicine, a cosmetic or a plastic to injurious actions of oxygen, heat and/or light.

Abstract: Production of highly pure phytantriol (I) comprises rectification of (I) in a fine vacuum in columns with ordered metal fabric packing and duct distributors with ≥ 500 dripping points/m at an angle of 90 degrees to the layer of fabric just below them. There are 2 or more, 20-100 mm high packing elements with layers of fabric at 90 degrees to one another. Strictly adiabatic rectification with absolute exclusion of air is used. Production of highly pure phytantriol (I) comprises rectification of (I) contaminated with lower and/or higher boiling by-products in a fine vacuum in columns containing metal fabric packing with ordered structure. The liquid is distributed with duct distributors with ≥ 500 dripping points/m . The ducts are at an angle of 90 degrees to the layer of fabric directly below them in the packing. There are 2 or more packing elements with a height of 20-100 mm and layers of fabric at 90 degrees to one another, below the distributor. The process is operated with absolute exclusion of air. Strictly adiabatic rectification is used.

Abstract: Chromanyl-ascorbic acid derivatives of formula (I) are new. R1 = 1-12C aliphatic hydrocarbyl; or 4-12C cycloalkyl, aryl or heterocyclyl (optionally substituted by one or more alkyl, alkoxy, OH, NH2 or mono- or dialkylamino); R2 = 8-30C (especially 12-24C) hydrocarbyl, 1-6C alkyl (optionally substituted by COOH); or 4-20C cycloalkyl, aryl or heterocyclyl (optionally substituted by one or more alkyl, alkoxy, OH, NH2 or mono- or dialkylamino); R3 = PO3H2 or glycosidyl; R3-R5 = H or 1-20C alkyl, cycloalkyl, aryl, aralkyl, cycloalkylalkyl or COR7 (sic); or R4 + R5 = alkylene optionally substituted by one or more alkyl; R6 = H or COR7; and R7 = H, 1-20C aliphatic hydrocarbyl or phenyl-vinyl. N.B. R3 is defined twice in the main claim, but in dependent claims is defined once with R4 and R5 (see "More Specifically").
