Usage

Chemical Properties

Different sources of media describe the Chemical Properties of 122-91-8 differently. You can refer to the following data:
1. Colorless liquid; lilac odor. Soluble in 5.5 volumes of 70% alcohol. Combustible.
2. Anisyl formate has a floral, sweet, floral, herbaceous-green odor.

Occurrence

Reported found in Vanilla fragrans and Ribes species.

Uses

Different sources of media describe the Uses of 122-91-8 differently. You can refer to the following data:
1. Perfumery, flavoring.
2. Anisyl formate is a synthetic flavoring agent that is a fairly stable, colorless to light yellow liquid of floral odor. It should be stored in glass, tin, or resin-lined containers. It is used in berry flavors for applications in beverages, candy, and baked goods at 3–10 ppm.

Preparation

By direct esterification of anisic alcohol with formic acid.

Aroma threshold values

Odor characteristics are sweet, spicy, vanilla-like with powdery fruity nuances.

Taste threshold values

Taste characteristics at 50 ppm: sweet, vanilla, spice, with fruity heliotropine-like nuances.

Flammability and Explosibility

Notclassified

Metabolism

Esters of benzyl alcohol, such as the acetate, are rapidly hydrolysed in vivo to benzyl alcohol, which is then oxidized. The expected general reaction of primary aromatic alcohols in the animal body is oxidation to the corresponding aromatic acid, which is usually excreted as a glycine conjugate and to a lesser extent as an ester glucuronide. In rabbits, benzyl alcohol is almost entirely converted to benzoic acid, which is excreted mainly as hippuric acid . In substituted anisoles with a carboxyl group or a potential carboxyl group attached to the aromatic ring, the ether link is relatively stable(Williams, 1959).

Application of polydopamine sulfamic acid-functionalized magnetic Fe3O4 nanoparticles (Fe3O4@PDA-SO3H) as a heterogeneous and recyclable nanocatalyst for the formylation of alcohols and amines under solvent-free conditions

Herein, formylation of structurally different amines and alcohols with ethyl formate was carried out in the presence of a catalytic proportion of sulfonic acid supported on polydopamine (PDA)-encapsulated Fe3O4 nanoparticles as a heterogeneous, recyclable, and greatly efficient catalyst; this method provided the corresponding N-formyl compounds in good to excellent yields under solvent-free conditions. The magnetically catalytic system was recovered, by-passing the time-consuming filtration operation using an external magnet device. This procedure also increases the purity of the product and promises economic and ecological advantages. Furthermore, the recovery and reuse of the catalyst was demonstrated five times without detectable loss in the activity.

Br?nsted acidic ionic liquid supported on rice husk ash (RHA-[pmim]HSO4): A highly efficient and reusable catalyst for the formylation of amines and alcohols

In this work, rice husk ash (RHA), as a natural source of amorphous silica, was used as a support for the immobilization of 1-methyl-3-(trimethoxysilylpropyl)-imidazolium hydrogen sulfate. The immobilized acidic ionic liquid was characterized with a variety of techniques including infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), scanning electron microscopy (SEM) and pH analysis. The catalytic performance of this heterogeneous ionic liquid was probed for the N-formylation of a variety of amines using formic acid under solvent free conditions. It is also useful for the formylation of benzylic alcohols. The procedure gave the products in excellent yields in very short reaction times. Also this catalyst can be reused ten times without loss of its catalytic activity.
