Бутилметакрилат

Description

Butyl methacrylate (n-butyl ester of methacrylic acid) is an acrylic monomer for radical polymerization. Chemical formula C8H14O2, CAS number 97-88-1. There is no input data for this product in the original dump; the description is compiled from verified reference sources.

Basic Attributes

• CAS No.: 97-88-1
• Chemical formula: C8H14O2
• Synonyms: n-butyl methacrylate, Blemmer BMA, butyl 2-methyl-2-propenoate, acrylic ester BMA, Visiomer n-BMA

Scope of application

Monomer for the production of homo- and copolymers of the acrylic series: polybutyl methacrylate and copolymers with other (meth)acrylates. It is used in the production of paint and varnish coatings, adhesives, binders for printing inks, as well as in dental and medical acrylic polymers, where it is valued for the elasticity imparted to the polymer compared to methyl methacrylate. Polymerizes by a radical mechanism initiated by peroxides or azo compounds.

Safety Information

Numerical physical and chemical parameters, GHS classification, transport codes and toxicological data for this item are not given in the source and are not substituted by analogy with related acrylates, so as not to distort the product card with unreliable values.

Storage and transportation

As an acrylic monomer, it requires storage with a polymerization inhibitor, in a cool, dark room, away from heat sources and radical polymerization initiators (peroxides, light).

Synonyms and alternative names

The compound is also mentioned in sources under the names: 2-Propenic acid, 2-methyl-, butyl ether; Methacrylic acid, butyl ether; n-butyl methacrylate; Butyl 2-methyl-2-propenoate; Acrylic Ester B; Blemmer B.M.A.; Butyl2-methylacrylate; NSC 20956.

Batch identification

For accurate batch identification: The CAS number 97-88-1 uniquely identifies the substance in the ECHA, PubChem and chemical supplier registries.

Elemental composition

The gross formula C8H14O2 shows the elemental composition of the molecule: 8 carbon atoms, 14 hydrogen atoms, 2 oxygen atoms.

Bottom line

Before using a batch of butyl methacrylate in production, it is recommended to request a current safety data sheet from the supplier indicating the flash point, density and GHS classification for the specific batch.

Related monomers

In the same series of alkyl esters of methacrylic acid, methyl methacrylate (a harder polymer) and ethylhexyl methacrylate (a softer and hydrophobic polymer) are of industrial importance - the butyl chain of butyl methacrylate gives the properties of the copolymer intermediate in elasticity and hydrophobicity.

Additionally

The lack of numerical data for this position is not uncommon for highly specialized monomers, the safety data sheet of which is provided by the supplier as a separate document upon request, rather than published in a general product card.
