Peach Powder Usage and Synthesis.

Peach aldehyde, chemical name γ-undecanolactone, peach aldehyde is not a real sense of aldehyde, but belongs to the lactone compounds, colourless to light yellow viscous liquid, with a strong peach aroma, is an important lactone spice, in osmanthus, jasmine, gardenia, lily of the valley, orange blossom, white rose, lilac, acacia and other aroma of the daily spices are often used, but also the preparation of peaches, melons, plums, apricots, It is also a good raw material for the preparation of peach, melon, plum, apricot, cherry, cinnamon and other food flavours.

It is almost insoluble in water, dissolved in ethanol and most common organic solvents, can be widely used in daily chemical flavours and edible flavours.

Uses of Peach.

Peach Aldehyde has a pleasant iris-like sweet fat aroma, and a peach flavour when diluted. It is used to formulate edible flavours such as peach; plum and apricot; cherry; and to blend floral flavours such as cinnamon; violet; jasmine and lilac. Can be used as soap; daily cosmetics and edible spices.

Preparation of Peach.

1, obtained by lactonisation of undecylenic acid in the presence of sulfuric acid. At 80 ~ 85 ℃ undecylenic acid and 1.15 times the mass of 80% of the sulfuric acid stirring reaction 4h, add water and stirring after static stratification, the organic layer washed with water, 15% sodium carbonate solution, water in turn. After drying and distillation under reduced pressure, collect 160 ~ 170 ℃ (1733.2Pa) fraction, that is, γ-undecanolactone.

2、Undecylenic acid obtained from castor seed oil by heating and cracking is heated and cyclised with the participation of sulfuric acid (80~90℃, 6~8h).

3、It is obtained by co-heating ω-undecenoic acid with sulfuric acid. During the reaction, the position of double bond is transferred from chain to β,γ position, and then endo-esterified.

4、By the addition of 1-octanol, methyl acrylate and the free radical of di-tert-butyl peroxide.

Product Method of Bulk Peach Powder.

Gamma-undecalactone is naturally present in cinnamon, peach and cream, but industrially obtained by lactonisation of undecylenic acid in the presence of sulphuric acid.

Undecylenic acid and 1.15 times the mass of 80% sulphuric acid were stirred and reacted at 80~85°C for 4h, stirred with water and left to stratify, daring the organic layer to be washed sequentially with water, 15% sodium carbonate solution and water.

After drying and distillation under reduced pressure, collect 160 ~ 170 ℃ (1733.2Pa) fraction, that is, γ-undecalactone.
