Aromatic Carboxylic Acid Esters at Landmark

Carboxylic acids is a homologous series in which the compounds contain a functional group called the carboxyl group (-COOH), and they are the most common type of organic acid. The general molecular formula for carboxylic acids is CnH2n+1COOH. Carboxylic acids contain at least one carboxyl group. Aromatic carboxylic acids contain at least one aromatic ring, examples: benzoic acid.

A carboxylic acid ester is an ester derived from a carboxylic acid, which has the following general structural formula.

R1 = H, alkyl, aryl
R2 = alkyl, aryl

e.g.:

The O=C—O group in a carboxylic acid ester is called the carboxylic acid ester group.

Aromatic carboxylic acid esters are the most common esters in organic chemistry. The term ester used without a qualifier usually means a carboxylic acid ester and the term ester group a carboxylic acid ester group.

Applications of Trans-cinnamic Acid

Trans-cinnamic acid, also known as (2e)-3-phenyl-2-propenoic acid or (E)-cinnamate, is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Trans-cinnamic acid is a sweet, balsam, and honey tasting compound and can be found in a number of food items such as maitake, mustard spinach, common wheat, and barley, which makes trans-Cinnamic acid a potential biomarker for the consumption of these food products. Trans-cinnamic acid can be found primarily in saliva. Trans-cinnamic acid exists in all living species, ranging from bacteria to humans. Trans-cinnamic acid is a non-carcinogenic (not listed by IARC) potentially toxic compound. Cinnamic acid is an organic compound with the formula C6H5CHCHCO2H. It is a white crystalline compound that is slightly soluble in water, and freely soluble in many organic solvents. Classified as an unsaturated carboxylic acid, it occurs naturally in a number of plants....

Fragrance or Flavor Odor Type Listing

Fragrance and flavor substances are comparatively strong-smelling organic compounds with characteristic, usually pleasant odors. The odors of single chemical compounds are extremely difficult to describe unequivocally. The odors of complex mixtures are often impossible to describe unless one of the components is so characteristic that it largely determines the odor or flavor of the composition. Although an objective classification is not possible, an odor can be described by adjectives such as flowery, fruity, woody, or hay-like, which relate the fragrances to natural or other known products with similar odors. Such as, Pure ethyl cinnamate has a fruity and balsamic odor. A few terms used to describe odors are listed below: Aldehydic odor note of the long-chain fatty aldehydes, e.g., fatty-sweaty, ironed laundry, seawater Animal(ic) typical notes from the animal kingdom, e.g., musk, castoreum, skatole, civet, ambergris Ba...

Which Method is Better to Repel Birds?

Birds can be friends of mankind and a symbol of beauty, but for growers, it might be a trouble. If it is not driven out in time, it will bring great losses. - Manual Bird Repellent After seeing birds, drive them away manually, paying particular attention to the early morning and evening periods (the harm is serious). Advantages: No other additional costs. Disadvantages: It is impossible for people to watch 24 hours. After all, they have to be busy with their own affairs. - Reflective Tape to Repel Birds Pulling this kind of reflective ribbon in the orchard stimulates the eyes of birds through the reflected sunlight to achieve the effect of repelling birds. Advantages: the method is simple and easy to implement, and does not require a large cost. Disadvantages: The effect of repelling birds is more obvious under sunny conditions; after a long period of use, the effect will be greatly reduced when ...
