Tributyl citrate to replace phthalate plasticizers in a new green products with a wide range of uses. Introduced TBC production methods and uses of proposed future development prospects.
HC pharmaceutical industry network With the rapid development of China's plastics industry, PVC (P VC ) As the main products of the plastics industry, their applications become more extensive. PVC, in particular, soft goods, in the process requires the use of a large number of plasticizers, currently used primarily phthalate plasticizer Esters Products. But because of the potential Cancer Sex, have strict control over its use abroad. China has also developed the related laws and regulations, will phase out phthalates in food packaging materials, medical devices and the use of children's toys. Therefore, traditional plasticizer applications is limited research and development of new, green plasticizer has become a top priority. Where TBC is a promising development and utilization of new green plasticizer.
1 TBC performance and use [1]
TBC (referred to as TBC), molecular formula C18H32O7, molecular weight 360.44, colorless or on yellow oily liquid, boiling point is 170 / 1,033 Pa, the density 1.042g/cm3, refraction rate (nD25) was 1.443-1.445, viscosity 31.9mP? s (25 ), freezing point -20 , soluble in acetone, carbon tetrachloride, mineral oil, acetic acid, castor oil, linseed oil, alcohol and other organic solvents . Insoluble in water, non-toxic tasteless, volatile small, heat, light, water, and Vinyl resin, cellulose acetate, butyric acid, acetyl cellulose, ethyl cellulose, benzyl cellulose, good compatibility. The growth of bacteria and not with anti-bacterial, non-irritating, with flame-retardant and biodegradability.
TBC because of cold, in cold regions can still use good bending resistance, then heat, light, water, sealing and not due to good thermal stability, color, non-toxic it Security durable, suitable Cooperation Food packaging, pharmaceutical packaging materials, plasma bags and disposable infusion tubes. TBC can be plasticized PVC, PE, PP and cellulose resin. The compatibility is good, in the amount of ethyl cellulose films up to 40%, a large amount of plastic film below 10%. TBC shared with other non-toxic plasticizer can increase the hardness of products, especially on the soft fiber ether is more applicable. TBC another antibiotic for the non-toxic, does not grow bacteria, but also a flame retardant, so the large amount of vinyl resin can be used for sheet, film, beverage management, food bottle seal, medical equipment and hospital within the walls, family, restaurants, hotels and schools, offices and public places of the wall, ceiling, especially canteen Zaojian, bathroom, dining and other flame-retardant plasticizer required sterilization of plastic. Transport vehicles, trains, ships, aircraft and defense of military vehicles, tanks, warships, submarines, space facilities also need to use plastic products such plasticizers. TBC as nitrocellulose solvents can improve the ability of nitrocellulose UV resistance, good solvent is a variety of spices. TBC polylactic acid and its esters and compatibility with biological, ecological security, non-toxic, biodegradable ester thermoplastic. It is with good mechanical, optical transparency, good processing performance. Medical implants for the orthopedic surgical sutures, bone screws, drug packaging and drug release agent, such as insulin-layer tablets of polylactic acid, polylactic acid cylinders celebrate kanamycin, growth hormone releasing hormone in the massive implantation agent norethindrone acetate hollow fiber PLA agent. Polylactic acid or ester of the skeleton of inflammation in the body low intensity, the blood vessels, ligaments, skin, liver and other rehabilitation and training in use; polylactic acid or ester of the diaphragm repair detached retina of the eye. Biopolymers in food packaging bags, packaging materials, pharmaceuticals, plastic sheeting, fertilizer, trash bag there is, is practical. TBC can be used to improve the use of polylactic acid and its esters of. With TBC film extrusion mechanism, can reduce the glass transition temperature, improve the elongation at break. Membrane can be hydrolyzed into CO2 and H2O, do not pollute the environment, protect the natural environment.
TBC and acetic anhydride under the catalytic synthesis of acetyl tributyl citrate, its volatile than TBC, superior performance, is non-toxic and tasteless use of a broader "green "plastic plasticizer. Can be used for polyvinylidene chloride stabilizer, film and metal bonded conditioner, long soak in the water still has a very high adhesion. TBC can be used as a substitute for water pollution control, improving cleaning ability of detergent. TBC can be used for cosmetic additive, emulsifier, on the injured skin can play the role of treatment and nutrition, but also to prevent water evaporation of UV on the skin stratum corneum, protecting the skin with wetting and physical flexibility. In the tobacco industry, tobacco combustion gas is generated when the HCN, while the TBC can be absorbed in the tobacco HCN, thus reducing the toxicity of smokers by. TBC also allows cigarettes to maintain toughness and easily broken; TBC can be used for lubricants and anti-friction agent, smoothing agent is polyvinyl chloride resin; In addition, protein-containing liquid can be as foam remover, paper, flavoring agent, rubber scorch agent.
