ROHM AND HAAS COMPANY

Rohm and Haas Company's patent strategy reveals a strong historical focus on materials science, with Coating Compositions (Paints, Inks) representing 29.5% of its portfolio. While several materials categories like Polymer Synthesis (Polymerization) and Polymer Additives saw significant growth in 2024 (41.4% and 100.0% YoY respectively), the sharp declines across most categories in 2025 and so far in 2026, such as Adhesives dropping by 84.6% YoY in 2026, suggest a broad shift in patenting priorities or a strategic re-evaluation of its core materials innovations.

PROCESS FOR RECOVERING ACRYLIC ACID VALUE FROM HEAVY WASTE BYPRODUCTS

Filed:2025-11-17Pub:2026-06-11
Applicant:Dow Global Technologies LLC

A process for producing acrylic acid and recovering acrylic acid from Michael addition products comprises feeding a crude acrylic acid stream to a dehydration tower to produce an overhead stream comprising noncondensibles and lights and a bottoms stream comprising acrylic acid and Michael addition products of acrylic acid. At least a portion of the bottoms stream from the dehydration tower is fed to a finishing tower to distill the bottoms stream of the dehydration tower to produce a side draw stream comprising acrylic acid, and a bottoms stream comprising acrylic acid and Michael addition products of acrylic acid. Optionally, acrylic acid from the acrylic acid-rich stream is fed to an esterification process and/or a purification process. The esterification process produces an acrylic acid ester from the acrylic acid-rich stream, wherein a waste stream from the esterification process comprises Michael addition products of acrylic acid. The purification process produces a purified acrylic acid stream from the acrylic acid-rich stream, wherein a waste stream from the purification process comprises Michael addition products of acrylic acid. At least a portion of the bottoms stream from the finishing tower and/or the waste stream from the esterification process and/or the purification process is fed to a distillation column. A distillate comprising acrylic acid and a bottoms stream comprising the Michael addition products of acrylic acid are removed from the distillation column. At least a portion of the bottom stream from the distillation column is fed to a dimer cracker reactor. Acrylic acid is recovered from a vapor stream exiting the dimer cracker reactor.
