Physical and Chemical Properties	Ethyl ester of cellulose. White to light gray diffuse paste, thermoplastic. It is unstable to heat, discoloration at high temperature (240 ℃) and loses its original physical and chemical properties. Commodity grade products should have a specified viscosity. The relative density is 1.07~1.18, the refractive index is 1.47, and the softening point is 100~130 ℃, which can form a tough film and maintain flexibility at low temperature. Can be mixed with resin, wax, oil, etc. Stable to alkali and dilute acid. The softening point and hygroscopicity decreased with the increase of ethoxy content. The ethoxy content of standard commodities is 47% ~ 48%. Almost insoluble in water, glycerol and propylene glycol, but soluble in certain organic solvents to varying degrees (depending on the ethoxy content). Ethyl cellulose with ethoxy content less than 46% ~ 48% is easily soluble in a mixture of tetrahydrofuran, methyl acetate, chloroform and aromatic hydrocarbon-ethanol. Ethoxy content greater than 46% ~ 48% is easily soluble in ethanol, methanol, toluene, chloroform and ethyl acetate. The litmus test of 5% suspension was neutral.
Use	Used as adhesive and wire paint

Reference Information

identification test	solubility practically insoluble in water, glycerol and propylene glycol. But it is soluble in some organic solvents in different degrees (depending on the content of ethoxy groups), and when the content of ethoxy groups is less than 46% ~ 48%, it is easily soluble in Tetrahydrofuran, methyl acetate, chloroform and aromatic hydrocarbon-ethanol mixture; ethoxy group content is greater than the above, soluble in ethanol, methanol, toluene, chloroform and ethyl acetate. According to the OT-42 method. Take 5g of sample, dissolve in 95g of toluene ethanol mixture (80:20,W/W), the solution should be stable, transparent, yellowish. Several milliliters of this solution were transferred to a test tube or a glass plate and left to evaporate, with subsequent clouding and thickening until the residue became a transparent film. The film was flammable.
content analysis	accurately weigh about 50mg of sample pre-dried at 105 ℃ for 2H, it was placed in a gelatin capsule of known weight and placed in a flask of a methoxyl device, and then measured by the method of GT-14. Each milliliter of 0.1mol/L sodium thiosulfate corresponds to 751 μg of ethoxy (-OC2 H5).
toxicity	ADI is not specified (FAO/WHO. 2001). Safe for use in food (FDA,§ 172.868,2000).
Use	tablets (mostly used for vitamins and inorganic salts); Binders for vitamin powder; Fillers; dilute pigments and other food additives used as adhesives and wire paints used in ink, coatings, adhesives, pharmaceuticals, cosmetics and food fields, also used as fillers, binders, etc. Ethyl cellulose is used in large quantities for coatings. It can also be used as the basic material of solid lubricant for metal workpiece stamping. In microcircuit printing, ethyl cellulose is used as a vehicle. In the radio industry, it is used as an advanced insulating material and in protective coatings as a cladding of special films, such as rocket propellants. It can be used as hot-melt adhesives and coatings for cables, paper, textiles, etc., and can also be used as insulation for extrusion lines and as a toughness enhancer for plastics. It can also be used for pigment grinding base, for printing ink, for molding plastic powder, for explosive fuze, and for vitamin formulation. It is used as a peelable protective layer against corrosion and damage of metal parts before use, and can also be used as a peelable coating to protect fragile glassware. In adhesives, textiles and fibers, medicine and food, and other industries, there are many uses. Industrial grade ethyl cellulose is used in coatings (gel-type coatings, hot melt coatings), inks (screen printing inks, gravure printing inks), adhesives, pigment pastes, etc. High-grade products are used in medicine, cosmetics and food, such as pharmaceutical tablet packaging materials, long-acting formulations with binders.
method of production	alkaline fibrils were prepared from refined pulp or Linter with sodium hydroxide. Alkaline cellulose is then reacted with ethyl chloride in an autoclave to replace all or a portion of the three hydroxyl groups in glucose with ethoxy groups. The reaction product was washed with hot water and dried to obtain ethyl cellulose. wood pulp or Kapok is prepared by alkali treatment and then ethylation of alkaline cellulose with ethyl chloride. Cellulose and ethanol are combined in the presence of a dehydrating agent.
spontaneous combustion temperature	698 ° F.
