Citral also be synthesized in a laboratory by chemical reaction, making it a popular aroma chemical in the fragrance and flavor industry. Its strong citrus scent makes it a popular choice for products that aim to capture the refreshing and invigorating qualities of citrus fruits.

Here is the process of synthetic Citral production : 

Citral can be synthesized through several different processes, but one common method involves the reaction of geraniol and citronellal. Here are the steps involved in this process:

1. The starting materials, geraniol and citronellal, are mixed together in the presence of an acid catalyst, such as sulfuric acid or p-toluenesulfonic acid.

2. The acid catalyst helps to facilitate a dehydration reaction, where water is removed from the two starting materials, resulting in the formation of citral.

3. The crude citral mixture is then typically purified through distillation, where the citral is separated from any remaining starting materials or byproducts.

4. The purified citral can then be used in various applications, such as in the production of fragrances, flavorings, and other aroma chemicals.

It's worth noting that there are other methods for synthesizing citral as well, such as through the oxidation of limonene or the pyrolysis of citric acid. The specific synthesis method used will depend on various factors, such as the availability of starting materials, desired purity of the final product, and cost considerations.
