Undecanal Uses

  1. Undecanal is widely used in fragrance formulations. A small amount (<0.5%) is used for rose, tuberose, acacia, orange blossom, jasmine, iris and other floral scents. Can also be used as a top note for citrus and other fruity aromas. Also used in fantasy fragrances. It can be used in the preparation of lemon, white lemon, orange, orange, cucumber, honey, fresh and various fruit-flavor compounds and gum flavors.
  2. Undecanalshi GB 2760–1996 stipulates that it is allowed to use edible spices. It is mainly used to prepare flavors from lemons, lemons, oranges and other citrus and cucumber, honey and gum.
  3. Undecanal has rose fragrance in diluted state; floral fragrance; fruit fragrance and sweet orange fragrance, used as a floral fragrance extracting agent, used in cosmetics; in soap essence.

Undecanalde App

Methylnonylacetal is an important raw material for the preparation of modern fragrances, with aldehyde aromas accompanied by ambergris, citrus and vanilla aromas. Because of its strong aroma, good diffusivity and long fragrance retention time, it is often used as the top incense for aldehyde aroma, and can also be used for the preparation of tobacco, amber and other flavors. In addition, it can also be used directly as a raw material for cosmetics and food flavors. CN201810211803.X provides a method for synthesizing methyl nonacetaldehyde.

Including (a) using n-Undecanal and formaldehyde as raw materials in solvent methanol, using morpholine/acetic acid as catalyst, wherein n-undecanal is added dropwise into the reaction system, and reacted at 70-80 ℃ to form sub- Methylundecanal; (b) using methyleneundecanal as raw material, palladium/carbon as catalyst, hydrogenation reaction to generate methylnonacetaldehyde. The synthetic equation of this synthetic method is:

The present invention adopts morpholine/acetic acid as the catalyst for the aldol reaction, the reaction conditions are mild, and the selectivity is high. Further, the present invention adopts the dropwise addition method to add n-undecanal, reduces the generation of side reactions, and improves the selectivity and yield of the reaction; Sex is high. It has the advantages of high reaction selectivity and high yield.

The existing environmental protection wall coatings are divided into water-based latex coatings and oil-based environmental protection wall coatings. The construction of water-based latex paint is greatly affected by temperature, so it cannot be applied in colder areas, and it also has requirements on humidity. When the humidity is high, the drying period is too long. In addition, the existing water-based latex coatings have poor anti-fouling performance, do not have good water resistance and wear resistance, are easy to chalk, fade, have poor anti-aging properties, and have problems such as low gloss of the coating film. CN201511015561.X provides a durable new latex paint and a preparation method thereof, which have the advantages of less volatile organic compound content, less environmental pollution, energy saving, emission reduction, low carbon and environmental protection.

In order to solve the above-mentioned technical problems, the technical scheme adopted in the present invention is that a durable new latex paint is made from the following raw materials in parts by weight: 15-22 parts of white latex, 3- 7 parts, 2.5-6.8 parts of light calcium carbonate, 10-30 parts of deionized water, 2.5-3.7 parts of oxalic acid, 2.5-6.8 parts of Undecanal and 3.8-9.5 parts of ethyl 2-chloro-3-oxobutyrate. Optimized, the above-mentioned durable new latex paint is made from the following raw materials in parts by weight: 19 parts of white latex, 5 parts of 5-methyl-1-hexanol, 4.2 parts of light calcium carbonate, 18 parts of deionized water, 3.1 parts of oxalic acid, 4.2 parts of Undecanal and 6.9 parts of ethyl 2-chloro-3-oxobutyrate.

Compared with the existing product, the present invention improves the mildew resistance and scrub resistance of the latex paint after mixing oxalic acid, Undecanal and ethyl 2-chloro-3-oxobutyrate, improves the life of the finished latex paint, and can Widely used for wall painting.

CN200810158983.6 provides a kind of rose essence for lip balm which has the advantages of very little dosage, pure and rich fragrance and strong durability.

The rose essence for lip balm of the present invention is refined by adopting the components and weight percentages of the following formulas: ethyl citronellal 0.8%-1.0%, hydroxycitronellal 5.0%-6.0%, Hexalaldehyde 1.0%~1.3%, ketone musk 0.9%~1.1%, musk 1.0%~1.1%, rose 2.0%~2.3%, citronellyl acetate 1.0%~1.1%, geranyl acetate 2.0%~2.2% , Geranyl butyrate 1.8%~2.0%, Phenylacetic acid 0.1%~0.2%, Agaryl acetate 4.0%~4.5%, Geraniol 20.0%~22.0%, Vanillyl alcohol 10.0%~12.0%, Agaryl alcohol 5.0%~6.0%, rositol 5.0%~6.0%, cinnamyl alcohol 2.0%~2.5%, phenethyl alcohol 20.0%~22.0%, geraniol 10.0%~11.0%, nerol 3.5%~4.0%. The advantages of the present invention are: the lip balm of the above formula has convenient source of raw materials of rose essence, pure and rich fragrance, strong persistence, and very little dosage, and the general dosage is 0.5%-1.0%.

Undecanal Preparation

① It can be obtained by oxidation of undecanol or reduction of undecanoic acid.

② It can be prepared by catalytic hydrogenation of methyl undecenoate to produce undecanol, and afterwards catalytic dehydrogenation under the activity of copper driver.

③ Utilizing α-hydroxylauric acid as basic material, it can be gotten by catalytic oxidation.

④ Hydrogenation of methyl undecenoate, a by-product in the preparation of n-heptaldehyde, to produce undecanol, which is after that prepared according to the ② approach or the ① technique.
