Dialdehyde Starch | 9047-50-1

Dialdehyde starch is a modified product treated with a specific chemical process to produce a highly reactive and versatile material. It is typically made by oxidizing native starch with a particular chemical reagent to create an aldehyde functional group.

Uses of Dialdehyde starch

One of the primary uses of dialdehyde starch is as a crosslinking agent in producing paper and paperboard. It improves the paper’s physical and mechanical properties by enhancing its wet strength and reducing porosity. Dialdehyde starch is also used to produce textile coatings, improving the fabric’s performance, stability, and durability.

Another essential application of dialdehyde starch is as a raw material in producing biodegradable polymers. It can be used as a starting material in making various bio-based materials, including films, coatings, and adhesives.

Dialdehyde starch is a non-toxic, biodegradable, and sustainable material, making it an eco-friendly choice for various applications. It is a safe and reliable material with excellent stability and compatibility with other materials.

Dialdehyde starch is a highly versatile and reactive material that finds numerous applications in various industrial sectors, including paper and paperboard production, textiles, and biodegradable polymer production. Its eco-friendly properties, stability, and compatibility make it an ideal choice for many manufacturing processes.

Dialdehyde Structure

Dialdehydes are chemical combinations with two aldehyde functional groups (-CHO) linked to a single molecule. The standard procedure for dialdehydes is R-CHO-CHO-R’, where R and R’ are organic groups or atoms connected to carbonyl groups.

The simplest example of a dialdehyde is formaldehyde (methanal), which has both aldehyde groups connected to the same carbon atom, resulting in a structure similar to -OHC-CH2-CHO. The two aldehyde groups are attached to distinct carbon atoms in more complicated dialdehydes, such as glutaraldehyde (1,5-pentanedial).
