V kemični industriji je 1, 3 - butadiene je pomemben surovina . To je brezbarven, vnetljiv plin z rahlim sladkim in cvetnim vonjem .
Edinstvene lastnosti postavljajo temelje za uporabo
Melting point of 1,3-butadiene: -108.9℃, boiling point: -4.4℃. It is insoluble in water but readily soluble in most organic solvents. The conjugated double bond structure of its molecule endows it with unique chemical reactivity, enabling reactions such as addition, Sinteza diene in polimerizacija, ki zagotavljajo možnosti za raznolike aplikacije .
Široko uporabljeni, prodirajo v vsak kotiček življenja
Jedrna surovina na polju sintetične gume
1, 3- butadiene je "steber" proizvodnje sintetične gume . nepogrešljiv je za izdelke, kot sta stirensko-butadinska guma in nitrilna guma
Pomemben udeleženec v industriji sintetične smole
Kopolimeriziran je s stirenom, da tvori smole, kot so ABS, MBS in SBS, ki se pogosto uporabljajo v proizvodnji, gradbeništvu in drugih poljih gospodinjstev .
Osnovna surovina v finih kemikalijah
V finih kemikalijah lahko pripravimo antrakinonske derivate in tetrahidroftalični anhidrid, ki se uporablja pri proizvodnji barvil, zdravilnih sredstev, topil itd. .
Neprekinjene inovacije v tehnologiji priprave, raziskovanje zelenih in učinkovitih poti
In the early days, it was prepared through methods such as the acetylene method. Currently, it is mainly extracted from the C₄ fraction of cracked naphtha, but there are shortcomings. Recently, Professor Zhang Jian's team from Northwestern Polytechnical University achieved a breakthrough. Their developed tri-nuclear Cu₃-MOF Catalyst je dosegel 91 -odstotno selektivnost za 1, 3- butadiena in visok donos 64 mmol g⁻¹ h⁻¹ pod specifično gostoto, kar je spodbujalo zeleni razvoj .
Spremembe v vzorcih, priložnostih in izzivih na trgu in povpraševanju sobivajo
The global annual demand for 1,3-butadiene exceeds 12 million tons, with an annual growth of approximately 5%. China is the largest producer and consumer, and the supply entities are increasingly diverse. However, due to the lightening of ethylene raw materials, the production capacity is low and growth is slow, while the demand side continues to grow, but also faces okrepljena konkurenca in drugi izzivi .
1, 3- butadiene ima pomemben položaj na kemičnem polju in pričakuje se, da bo v prihodnosti igrala večjo vlogo na več poljih .
