content analysis | Method 1: determination by non-polar column method according to General Gas chromatography (GT-10-4). Method 2 a sample of about 1 g is precisely weighed and then quantified according to Method 1 in the aldehyde and ketone assay (OT-7), except that the standing time is changed to 15 min. The equivalence factor (e) in the calculation is taken as 64.11. Method Three was determined by aldehyde assay (OT-6). The amount of the sample was 1.5g. The equivalence factor (e) in the calculation is taken as 64.11. |

Use | is one of the components of Rose head fragrance, and is also used for sweet orange flower, orange flower, bergamot and citrus Gulong type. Can also be used in trace amounts of imitation cream, chocolate, apricot, plum, grape, lemon, orange, cheese and other food flavors. octanal has a strong fruit aroma, and has a pleasant sweet orange aroma when it is extremely thin. China's GB 2760-86 provides temporary use of edible spices, which are mainly used for the blending of citrus spices, in beverages, ice cream, candy, bread, etc. in the amount of 1.4-4.4ppm, can also be used as soap, detergent spices. Octanal is also an intermediate in organic synthesis. GB 2760-1996 provides temporary permission for the use of flavorants. Mainly used in the preparation of apricot, plum, cream, chocolate, grape and citrus flavor. Dosage is generally <10mg/kg, so as to avoid bad oil odor. |
production method | is obtained from the oxidation of octanol by copper, platinum, silver oxide treated copper mesh and the like. Octanoic acid was prepared by nickel catalyst at 300 °c. octanol or octanoic acid may be used as a raw material. Octanol is oxidized in the presence of copper chromium catalyst to produce octanal. Octanal can be produced in 300 yield using a variety of methods for producing octanoic acid from octanoic acid, for example by mixing octanoic acid vapor with excess formic acid vapor over a titanium oxide or manganese oxide catalyst at 90% °c. |
