Helional Uses

Helional can be used in daily chemical fragrance formulations, mainly for the deployment of various floral fragrances such as jasmine and rabbit grass. It can be used in the blending of almost all floral fragrances such as cyclamen, jasmine, lily of the valley, lilac, rose, etc., including various international famous brand perfumes. It is an indispensable precious spice.

Preparation Method of Helional

Foreign countries have been researching and developing the synthesis and application of Helional since the 1950s, and have mastered the core synthesis technology. However, there are few domestic reports on the synthesis and application of Helional. The synthesis yield is too low, the side reactions are serious, and the environmental pollution is serious. Difficult to achieve industrialization.

Tang Jian (Synthesis of Helional [J]. Guangxi Chemical Industry, 1998, 27 (3): 33~36) introduced the Claisen-Schmidt condensation reaction with piperonal and propionic acid, and used an inorganic strong base as a catalyst to generate piperonyl Propylaldehyde (α, β-unsaturated aldehyde) is selectively reduced by hydrogenation to obtain new jasmonal, and its main reaction conversion rate is 56%. Because the catalyst is too basic, side reactions such as disproportionation are prone to occur, and the yield decreases and reaction products are difficult to purify and separate.

A kind of preparation method of optimized Helional, its special feature is that, described new foreign jasmonal takes piperonal as starting material, strong basic anion exchange resin catalyzes, and propionaldehyde takes place Claisen-Schmidt condensation reaction, obtains Piperonyl propionaldehyde, and then catalytic hydrogenation, to obtain Helional.

Helional Adds a Little Foreign Flavor to Daily Chemical Essence

Helional is also called “Piperonal”. In many books introducing spices and essences, the aroma of jasminal is described as the so-called. The “sunflower” aroma of Helional, in fact, the aroma of Helional should be a bean aroma with fennel flavor, which has nothing to do with the “floral fragrance”. This spice is also more prone to discoloration, especially if it encounters a small amount of indole, it will also turn pink, so you need to pay attention. In soap essence, bean fragrance is very important, coumarin is the “first” because of its cheap price and no risk of discoloration, but the aroma of coumarin is “too monotonous”, adding some jasmonal will make it A kind of “exotic flavor” (the so-called “foreign flavor”) is more able to touch the hearts of consumers. When Helional is added in a large amount, especially when there are nitro musks (musk sunflower, dimethyl, musk benzene, and musk ketone, etc., it is best to add some geraniol to make the produced look stable. Discoloration.

Helional is obtained by using jasminal as raw material, first condensing with propionaldehyde, and then selective catalytic hydrogenation. Its aroma has basically broken away from the “frame” of Helional, with green, aldehyde, and ozone-like aromas, and the floral aroma is not too obvious, but it makes people feel the smell of cucumber, and this green aroma can be found in essence throughout. The main deployment of fragrance type essence is optional.

Among all the green fragrances, the privet aldehyde fragrance has a higher specific strength value. Adding a little bit to various essences will reveal the “green” flavor; It smells like green! In the “classification of spices”, no one will put it in any group of spices other than “green fragrance”. Once the aroma of privet aldehyde is exposed, it will give people a “pungent” feeling. At this time, it is best to add other green fragrances such as citrus aldehyde, leaf alcohol, leaf acetate, salicylate, sevita, and cyanin , linalool, olive green ketone, phenylacetaldehyde, watermelon aldehyde, etc. make the head fragrance less “pungent”

Citrus aldehyde has a higher aroma ratio, but it is not as “sharp” as privetal, and it can also “shave off” the “sharp-thorny” smell of privetal. Therefore, whenever privet aldehyde is used in the essence, almost 3 to 10 times the amount of citrus green pendant will be added. Green aldehyde is the “peacemaker” of many green fragrances, and it is found in most green fragrances. It’s “shadow”.
