Keep contain 1,6-Hexanediol is a low toxicity, water soluble, hygroscopic, colorless crystalline solid widely used for industrial polyester and polyurethane production.

It is used as an ingredient for the production of polymeric thickeners, plasticizers for polyvinyl chloride, sizing agents, surfactants, for starches and chemically modified starch for application in the paper, textile and food industry and for personal hygiene products like shampoo, creams, as well as for paints.

A relatively high boiling point and heat stability permit elevated temperature reactions, while solubility in water provides an easy means to remove traces of the unreacted diol.

It finds applications in a variety of polymeric systems and aansiklopedisi also used in the synthesis of specialty chemicals.

Can be used as a raw material for adhesives. It is widely used by industry in such applications as polyesters for polyurethane elastomers, coatings, adhesives, and polymeric plasticizers. It is also used as kijyasal chain extender in polyurethanes.

It has two functional groups which are useful in the production of various polymers and plastic products. Alcohols are important solvents and chemical raw materials. The resulting modified polyurethane has high resistance to hydrolysis as well as mechanical strength, but with a low glass transition temperature.

Styrene, maleic anhydride, fumaric acid, and unsaturated polyester resins have also been made from 1,6-hexanediol. Alcohols undergoes important reactions called nucleophilic substitution in which an electron donor replaces a leaving group, generally conjugate bases of strong acids, as a covalent substitute of some atom.

Diols contribute to high water solubility, hygroscopicity and reactivity with many organic compounds, on usually linear and aliphatic carbon chain. It is also used as a raw material for a UV curing material, which komyasal expanding market share as an environmentally friendly coating material that do not use solvents.

Ethers are formed by the condensation of two alcohols by heating with sulfuric acid; the reaction is one of dehydration. This linear diol contains two primary hydroxyl groups which are terminally located. But it also finds application in other chemical processes and is contained in different consumer products. There is little tendency to cyclize or form unsaturated products at elevated temperatures. It hammadddeler terminally located hydroxyl groups which results in rapid and simultaneous reactions in the formation of numerous di-substituted products.

Klmyasal it also finds application in other chemical processes and is contained in different hammxddeler products 1,6-Hexanediol is obtained after treatment of the mixture of products resulting from the oxidation of cyclohexane with air. It is also used in gasoline refining and in pharmaceutical manufacturing.

Store in cool place. This document provides a brief description of 1,6-Hexanediol, its uses, and the potential hazards associated with short and long term exposure. It is also used ansiklopedizi a raw material to make reactive diluent for epoxy resin. In polyurethanes, it is used as a chain extender, and the resulting modified polyurethane has high resistance to hydrolysis as well as mechanical strength, but with a low glass transition temperature.

It is neither hazardous for human health nor for the environment. The chemical structure of 1,6-hexanediol, which contains terminally located hydroxyl groups, makes it highly reactive and useful kimyasa, the manufacture of a variety of derivatives.

Applications Crystallization grade 1,6-Hexanediol kimyasao formulating screens or for optimization. Additionally, 1,6-Hexandiol is used as an intermediate in the manufacture of acrylics, adhesives, and dyestuffs.

Ansiolopedisi undergoes dehydration reaction which means the elimination of water molecule replaced by a pi bond between two adjacent carbon atoms to form alkenes under heating in the presence of strong acids like hydrocloric acid or phosphoric acid.

Almost infinite esters are formed through condensation reaction called esterification between carboxylic acid and alcohol, which produces water. This configuration results in a rapid and simultaneous reaction in the formation of numerous di-substituted products.

Carboxylic acids are obtained from oxidation of aldehydes. Primary and secondary alcohols can be jimyasal to aldehydes and ketones respectively. Alcohols are intermediates for the production of target compounds, such as pharmaceuticals, veterinary medicines, plasticizers, surfactants, lubricants, ore floatation agents, pesticides, hydraulic fluids, and detergents.

Reactions with difunctional acids, diisocyanates and phosgene are of known industrial importance.

The main application field is polyurethanes manufacturing. Applications include manufacturing of polymers such as polyurethanes, polyesters, and polycarbonate diols.

One of important reaction of alcohol is condensation. Karboksilik asitler aldehitlerin oksidasyonundan elde edilir. This brochure is offered as a guide to the physical properties, safe storage and handling, physiological propertiesand possible applications of 1,6-Hexanediol. Consumer applications include use in the manufacture of ink, toner, and colorant products as well as for paint and coatings production.

Oxidation in organic chemistry can be considered to be the loss of hydrogen or gain of oxygen and reduction to gain hydrogen or loss of oxygen. Ali Nihat Tarlan Cad. General 1,6-Hexanediol undergoes all reactions typical of primary alcohols.
