13Benzenedimethanol

1,3-Benzenedimethanol, also known as m-xylylene glycol or isophthalyl alcohol, is an organic compound with the chemical formula C8H10O2. It is a diol, meaning it contains two hydroxyl (-OH) groups attached to a benzene ring. In this case, the two hydroxymethyl groups (-CH2OH) are attached to the benzene ring at the meta positions (1 and 3). It is a white crystalline solid at room temperature.

The synthesis of 1,3-benzenedimethanol can be achieved through various chemical routes. One common method involves the reduction of isophthalic acid or its derivatives, such as dimethyl isophthalate. This reduction is typically carried out using reducing agents like lithium aluminum hydride or catalytic hydrogenation. Another approach involves the hydrolysis of 1,3-bis(halomethyl)benzene.

1,3-Benzenedimethanol finds applications as a monomer in the production of polymers. It can be used in the synthesis of polyesters and polyurethanes, imparting specific properties to the resulting materials. Its rigid aromatic structure can contribute to increased thermal stability and mechanical strength in polymers. It can also serve as a cross-linking agent in certain resin formulations. Additionally, it is used as an intermediate in the synthesis of other organic chemicals.
