1,3-DIMETHOXYPROPANES CONTAINING 6,6-DIMETHYLBICYCLO[3.1.1]HEPTANE FRAGMENT OF NATURAL ORIGIN AND N-ALKYL SUBSTITUENT, METHOD FOR PREPARATION THEREOF AND TITANIUM-MAGNESIUM CATALYST FOR POLYMERISATION OF PROPYLENE, CONTAINING SAID COMPOUNDS IN ITS COMPOSITION Russian patent published in 2025 - IPC C07C43/115 C07C41/14 C08F4/649 C07B41/04 

FIELD: chemistry.

SUBSTANCE: present group of inventions relates to the field of organic chemistry, specifically to 2,2-dialkyl-1,3-dimethoxypropane, a method for production thereof, as well as use of propylene polymerisation catalyst as stereo-regulating component. 2,2-dialkyl-1,3-dimethoxypropane of formula 1 contains in its structure as one of alkyl groups (6,6-dimethylbicyclo[3.1.1]heptan-2-yl)methyl fragment, and as the second alkyl group R is a straight fragment of the composition R = n-C_mH_2m+1 (m = 1-8).

EFFECT: providing desired 1,3-diesters, a synthesis method thereof and use of titanium-magnesium catalysts as an internal donor for polymerisation of propylene, which enables to obtain polypropylene with a controlled molecular weight distribution depending on the introduced straight alkyl substitute.
