Contact information for the technology transfer agencies regarding acrylonitrile technology, MMA technology, and SAR process technology
Thread Content
Which expert could please provide contact information for companies that specialize in the transfer of technology related to acrylonitrile technology, MMA technology, and SAR processes? Thank you!
The poster should ask Sinopec Ningbo Engineering Company (formerly Lanzhou Design Institute); they are the only ones in China that have carried out design work for acrylonitrile.
The technologies required by the landlord cannot be independently developed domestically; thus, it’s still necessary to import technical software packages. I wonder when domestic engineering firms will be able to become true engineering companies—rather than merely doing design work for others without actually mastering the underlying technologies. Sadness is truly sad h
The original poster had better turn to the Lanzhou institute; acrylonitrile is their proprietary technology, and they are the only ones in China capable of producing it.
For MMA technology, it still depends on the raw material routes; after all, there are already at least four such routes, and the question raised by the original poster is rather vague. Jihua Company in China has large-scale facilities for propyl cyanohydrin production, using technology introduced from abroad. Shanghai has facilities using the C4 feedstock route, Singapore has ethylene carbonylation units in operation, as well as those using propylene as a feedstock. SAR is a very high-end polymer used in personal care products (diapers, sanitary pads), as well as in breeding in arid regions (as a water-retaining agent) and other applications. Key technologies include the preparation of polymer-grade acrylic acid and the ordered polymerization of acrylic acid. So-called ordered polymerization refers to controlling the molecular weight of the polymer through appropriate reaction conditions and initiator types, so as to reach the desired threshold. This technology is controlled by companies such as Nippon Catalyst in Japan, SNF in France, and Degussa in Germany; strict confidentiality measures are in place and the technology is never transferred. Domestic research still requires clear division of labor within a team, as well as patience; it’s impossible to succeed by being short-sighted and focusing only on immediate gains. Hehe
Jihua’s MMA is partially sourced from Longxin in Andahui; hehe, propylene cyanohydrin was introduced by ourselves. We can provide technologies for producing HCN and ACH through oil cracking, as well as MMA technology, hehe
Hello, poster. I have some information on this topic that I can provide; feel free to contact me at SUN7390359@163.com
Can you provide it on the 6th floor? Where did Andah’s Longxin technology come from?
Reply to post #5 by Dongfang Shikong: Brother, SAR refers to waste acid recovery technology; it’s not what you mentioned. What you referred to is called SAP resin.
Eastern Time tells the truth; it knows a lot and shows us the way. SAP, not SAR, is a superabsorbent acrylic resin. Technologies and devices are already available domestically. In MMA, domestic production also relies on C3 and C4 technologies.
It seems that currently in China, Jihua and Sinopec both have these three units.
