Tetrapropylene

Zouping Jinxing Chemical Co., Ltd. yog ib qho ntawm cov ua lag luam thiab cov muag khoom ntawm tetrapropylene hauv Suav teb. Yog tias koj yuav mus rau cov lag luam wholesale bulk tetrapropylene ua nyob rau hauv Suav teb, txais tos kom tau txais cov qauv dawb los ntawm peb lub hoobkas. Tag nrho cov khoom customized yog nrog cov khoom zoo thiab tus nqi qis.

Propylene undergoes oligomerization nyob rau hauv ib tug ruaj - txaj reactor siv SPA (khoom phosphoric acid) los yog ZSM-5/zeolite catalysts ntawm 200-240℃thiab nruab nrab siab, yielding ib tug sib tov C9 (trimer) + C12 (tetramer) + C15 kwj; cov C12 nqaim feem-propylene tetramer- yog tom qab cais tawm ntawm lub tshuab nqus tsev. Cov txheej txheem no feem ntau ua ke nrog lub nonene (propylene trimer) chav tsev, nrog rau tetramer ua ib qho khoom los yog cov khoom sib koom ua ke ntawm chav tsev trimerization.

Tert-dodecyl mercaptan (TDM): Ua los ntawm cov tshuaj tiv thaiv ntawm propylene tetramer nrog H₂S (catalyzed los ntawm acid av nplaum los yog resin); ua hauj lwm raws li ib tug tseem ceeb saw hloov neeg sawv cev / molecular hnyav regulator rau SBR, ABS, thiab nitrile roj hmab polymerization-tam sim no nws tseem ceeb tshaj daim ntawv thov.
Dodecylphenol (DDP): Siv los tsim dodecylphenol polyoxyethylene ether (ib qho tsis yog -ionic surfactant) thiab ua cov khoom siv raw rau Antioxidant 264.
T746 Rust Inhibitor: Ua los ntawm cov tshuaj tiv thaiv ntxiv nrog cov txiv neej anhydride los ua dodecenyl succinic anhydride; siv los ua xeb inhibitor hauv lubricants.
Branched-chain alkylbenzene (BAB): Siv nyob rau hauv industrial thiab hlau ntxuav cov neeg ua hauj lwm (raws li ib tug hloov rau tsis yog - zaub mov- qib LAS).
Lwm tus: Tert-dodecylamine; isotridecyl cawv / neotridecanoic acid (ntawm oxo synthesis tom qab hydrogenation); tetracosene (rau dimerization ntxiv); alkyldiphenylether disulfonate (tshwj xeeb surfactant rau latex thiab textiles).

Low to moderate acute toxicity (rat oral LD₅₀ in the >5 g / kg; Txawm li cas los xij, kev sib cuag ntawm daim tawv nqaij ntev ua rau defatting thiab tawg, thiab nws tseem ceeb heev rau qhov muag. GHS kev faib tawm: H315, H319, H304 (kev pheej hmoo ntawm aspiration pneumonia).
Flammable; flash point >70 degree, tseem tseem cais raws li cov kua combustible. Incompatible nrog muaj zog oxidizers thiab peroxide pib (vim reactivity ntawm olefinic daim ntawv cog lus).
Cia thiab thauj: Khaws hauv qab daim pam nitrogen lossis hauv lub tank tag nrho, tiv thaiv lub teeb; Ntxiv cov kab ntawm polymerization inhibitor (kom tiv thaiv me ntsis gelation thaum lub sij hawm ntev raug tshav kub). Regulated li Class 3 flammable kua (Packing Group III).
