1. Preparation of Benzene Styrene flame resistant material composition.
The structure of the flame-retardant Benzene Styrene material make-up is as complies with: by worsening 5.5 to 12 parts by mass (B) consisting of 2,4,6-tris Brominated fire resistant of (2,4,6-tribromophenoxy)-1,3,5-triazine, 0.5 ~ 5 components by mass (C) flame resistant aid, as well as 0.5 ~ 1.6 components by mass (D) lubricant, and also the (D) lube is two or more selected from the team consisting of (a) polyolefin wax, (b) greater fat amide, as well as (c) greater metal carboxylic acid salt.
Amongst them, the corresponding proportions of (D) lubes are: (a) 0 to 40% by mass, (b) 0 to 80% by mass, and also (c) 0 to 80% by mass, (a), (b) The total amount of as well as (c) is 100% by mass. Making use of a material structure that is exceptional in item stamina (screw helping to loosen torque after assembly and also detachment), and also has an excellent equilibrium of formability (fluidness, mold launch, and also scratch resistance) and also warm resistance (deflection temperature under lots) The advantages contribute to the progress of thinning printer toner cartridge containers used as inner parts of printers, faxes, and also copiers, and their industrial utility worth is very high.
2. Preparation of benzaldehyde, styrene oxide and also styrene cyclic carbonate.
Oxygen oxidation of Benzene Styrene generates mainly styrene oxide as well as benzaldehyde, both of which are extensively used as intermediates in the synthesis of great chemicals. Amongst them, because of the visibility of active epoxy teams, styrene oxide can react with numerous materials to develop high value-added substances, which are utilized in the fields of scent production as well as medicine preparation, such as the prep work of scent β-phenylethanol and also simidazole; benzaldehyde It can be used to synthesize artificial additive such as L-phenylalanine. Recently, with the sharp boost in demand for such fine chemical products, the oxidation of Benzene Styrene as well as benzaldehyde has actually attracted much attention despite in terms of commercial production or organic synthesis.
The technique consists of the adhering to actions: A) mixing Benzene Styrene, a solvent as well as a stimulant, and adding an oxidizing agent to accomplish an oxidation response to get a response feed fluid and also a mixed gas, the response feed fluid includes benzaldehyde as well as styrene oxide, as well as the mixed gas includes formaldehyde; B) dividing the response feed liquid so regarding obtain benzaldehyde and styrene oxide; C) performing catalytic oxidation therapy on the blended gas so as to convert formaldehyde right into carbon dioxide and water; and also D) making all the carbon dioxide including The blended gas is reacted with a part of styrene oxide to create Benzene Styrene cyclic carbonate.
