Usage

General Description

Octadecyl methacrylate is a chemical compound with the formula C23H44O2. It is a colorless, viscous liquid that is insoluble in water but soluble in alcohols, ethers, and hydrocarbons. Octadecyl methacrylate is commonly used as a monomer in the production of polymers and copolymers, such as acrylic resins and plastics. It is also used as a surfactant, lubricant, and as an ingredient in adhesives, coatings, and inks. Additionally, it is utilized in the manufacturing of emulsifiers and dispersants in various industries. Octadecyl methacrylate may pose health risks and safety precautions should be taken when handling and using this chemical.

Synthesis and single-chain folding of amphiphilic random copolymers in water

Amphiphilic random methacrylate copolymers, consisting of poly(ethylene glycol) (PEG) and alkyl pendent groups, undergo reversible single-chain self-folding in water via intramolecular hydrophobic interaction, to generate a dynamic unimolecular hydrophobic nanospace, similar in shape but structurally different relative to micelles and microgel star polymers. These copolymers were prepared by the ruthenium-catalyzed living radical copolymerization of a PEG methacrylate (PEGMA) and an alkyl methacrylate (RMA; R, -CnH 2n+1, n = 1-18), where copolymer composition, degree of polymerization, and hydrophobic R moiety were varied. Detailed structural and chain-folding characterization has revealed: single-chain folding is favored with the RMA content 20-40 mol % per chain; the hydrophobic inner compartment (or the self-folded structure) is stable even at a high polymer concentration (up to ～6 wt %); and folded-unfolded transition occurs on addition of methanol or by elevating solution temperature, finally to phase-separation above a lower critical solution temperature.

Preparation process of long-chain alkyl (meth) acrylate

The invention discloses a preparation process of long-chain alkyl (meth) acrylate, which adopts a polymerization inhibitor composition containing phenothiazine accounting for at least 10% of the totalmass of the composition as a polymerization inhibitor for esterification reaction. The invention solves the problem of self-polymerization in the post-treatment process, can effectively control the acidity of the product to obtain a colorless or white high-purity product, and has the advantages of high yield and expanded application range of the product; in addition, according to the preparationprocess, polymerized excessive (methyl) acrylic acid is recycled, so that a large amount of acid wastewater is prevented from being generated, and the comprehensive benefit is increased.

Process for producing methacrylic ester

A method of producing a methacrylic acid ester which comprises carrying out an ester-exchange reaction between methyl methacrylate and an alcohol or a phenol while removing by-product methanol as an azeotropic mixture with methyl methacrylate from the reaction system under reflux conditions, by the use of a reaction apparatus equipped with a distillation column. A methacrylic acid ester is produced with a good productivity by controlling the reflux ratio.
