Acetone is the organic compound with the formula (CH3)2CO. This colorless, mobile, flammable liquid is the simplest example of the ketones. Owing to the fact that acetone is miscible with water it serves as an important solvent in its own right, typically as the solvent of choice for cleaning purposes in the laboratory. More than 3 million tonnes are produced annually, mainly as a precursor to polymers.[2] Familiar household uses of acetone are as the active ingredient in nail polish remover and as paint thinner and sanitary cleaner/nail polish remover base. It is a common building block in organic chemistry. Acetone is naturally produced and disposed of in the human body as a result of normal metabolic processes. Reproductive toxicity tests show that it has low potential to cause reproductive problems. In fact, the body naturally increases the level of acetone in pregnant women, nursing mothers and children because their higher energy requirements lead to higher levels of acetone production. The medical community is now using ketogenic diets that increase acetone in the body to reduce epileptic attacks in infants and children who suffer from recalcitrant refractory epilepsy. Acetone is produced directly or indirectly from propylene. Most commonly, in the cumene process, benzene is alkylated with propene and the resulting cumene (isopropylbenzene) is oxidized to give phenol and acetone: C6H5CH(CH3)2 + O2 ¿ C6H5OH + (CH3)2CO This conversion entails the intermediacy of cumene hydroperoxide, C6H5C(OOH)(CH3)2. Acetone is also produced by the direct oxidation of propene with a Pd(II)/Cu(II) catalyst, akin to the Wacker process.
Beta Zeolite β Molecular Sieve For Catalyst Beta zeolite,having a unique three-dimensional 12-membered ring cross channel structure,is composed by mixing two polycrystals which are closely related to each other in the structure,and the two polycrystals are composed of the tetrahedral structure units which are symmetric based on the same center and arranged according to the layer.The two structures are composed of the tertiary structure units(TBU)which are symmetric based on the same center,wherein these TBUs are arranged in layer and subsequently connected in the form of left hand and right hand,This connection causes the twist along the channel of the direction C. Beta zeolite shows an excellent catalytic performance in catalytic cracking,hydrocracking,hydroisomerization,hydrodewaxing,aromatics alkylation,olefin hydration,olefin etherification and other petroleum refining and petrochemical processes. The varieties for the typical products of Beta Zeolite produced by JiuLong Chemical Co.,Ltd.are listed as follows,and the other products of this series also can be produced according to the requirements of the user: Detailed Product Description SiO2/Al2O3: 40 Color: White Powder Cation: Sodium SiO2/Al203: 25 SO4: 0.4 Cl-: 90ppm D50: 7um FCC catalyst , Beta Zeolite,Zeolite Beta,Beta Molecular Sieve SiO2/Al2O3 Mole Ratio: 25-40 Nominal Cation Form: Sodium/Hydrogen Na2O Weight %: 0.1 Surface Area, m2/g: 540 Zeolite beta β molecular sieves have three mutually intersecting 12-ring channels, it is only 12 yuan a three-dimensional pore structure of zeolite ring. β zeolite having high hydrocracking, hydroisomerization catalytic activity and adsorption capacity of linear paraffins, and good resistance to sulfur and nitrogen poisoning. It can be used in the petrochemical industry of benzene with propylene olefin system cumene, cumene metathesis diisopropylbenzene, toluene Isopropylation, aromatics alkylation, transalkylation diisopropylbenzene, propylene ether, methanol aryl structured, propylene oxide and acetic ether of phenol methylation, methylation of aniline, toluene transalkylation preparation of cumene and toluene disproportionation and transalkylation reaction with a catalyst such. β-type USY zeolite used in conjunction with the increase of the octane number of gasoline.
