Intermediates, cellulose ethers

Pentachloroethane is a good solvent for cellulose acetate, certain cellulose ethers, and for natural gums and resins, but its high toxicity has discouraged these uses. Pentachloroethane is still used as an intermediate in some tetrachloroethylene processes. 

Uses. May occur as an intermediate in the production of chlorinated ethylenes formerly used as a solvent for cellulose ethers, resins, and gums, for dry cleaning, coal purification, as a soil sterilizing agent, and as a chemical intermediate in the production of dichloroacetic acid... 

Uses The alicyclic hydrocarbons have numerous industrial applications. Cyclopropane (C3H6) is used as an anesthetic. Cyclohexane (CgH ) is used as a chemical intermediate as an organic solvent for oils, fats, waxes, and resins and for the extraction of essential oils in perfume manufacturing industries. Cyclohexene (C6H10) is used in the manufacture of maleic acid, cyclohexane carboxylic acid, and adipic acid. Methyl cyclohexane (C7H14) is used for the production of organic synthetics such as cellulose ethers. These compounds are used in different industries such as adipic acid makers, benzene makers, fat processors, fungicide makers, lacquerers, nylon makers, oil processors, paint removers, plastic molders, resin makers, rubber makers, varnish removers, and wax makers. 

Strong alkali solutions acting on cellulose (at room temperatures) produce alkali cellulose. The studies on the structure of alkali cellulose [43] obtained with 20-40% NaOH solutions indicated that the substance is not a true alcoholate but an addition complex, RceiiOH NaOH. A true alcoholate can be obtained, for example, from dry cellulose and Na in liquid ammonia. Alkali cellulose has a large range of applications as an intermediate product in the preparation of cellulose ethers, and xanthate (dithiocarbonate), as well as in cellulose mercerization. 

Use Organic synthesis (intermediate) solvent for cellulose ethers primer for diesel fuels. 

Use Chemical intermediate for dyes, flavoring materials, perfumes, and aromatic alcohols solvent for oils, resins, some cellulose ethers, cellulose acetate and nitrate flavoring compounds synthetic perfumes manufacturing of cinnamic acid, benzoic acid pharmaceuticals photographic chemicals. 

Use Solvent for nitrocellulose, some types of cellulose acetate, many cellulose ethers, many natural and synthetic resins, lacquers, perfumes, organic synthesis (intermediate), flavoring. 

OTHER COMMENTS used as a solvent for cellulose ethers and esters, dyes, and natural resins used in the manufacturing of phenolic resins and dark-colored thermosetting resins chemical intermediate for tetrahydrofurfuryl alcohol also used in the manufacture of wetting agents, furan polymers, corrosive resistant sealants and cements useful as a liquid propellant.

Butyl formate is a colorless liquid, miscible with alcohols, ethers, oils, hydrocarbons and so forth. It will dissolve cellulose nitrate, some types af cellulose acetate, and many cellulose ethers. Butyl formate will also dissolve many natural and synthetic resins such os copals, dammar, elemi, mastic, shellac, cumar resins, ester gum and alkyds in the presence of ethyl alcohol. It is used as an intermediate and in perfumes.

A number of business units have reeently been sold in an attempt to improve the eompany s financial position, which helps to explain the reduction in sales. They include the electronic materials imit to Carlyle, cellulose ethers to Shin-Etsu, and Lancaster Synthesis to Johnson Matthey. Further divestments are expected. Some of the companies sold were especially dependent on petroleum intermediates, and their loss makes Clariant feel less vulnerable to fluctuating crude oil price rises.
