Properties, application and production process of N,N'- methylene diacrylamide
Introduction to the
N-n '-methylene diacrylamide is an amine organic substance and is widely used as a chemical reagent. In the textile industry used in the production of thickeners, adhesives, in the production of oil exploitation in plugging agents, leather chemical, printing and other fields also have more applications, is the market application of a more stable quality, high purity, good performance of cross-linking agent, which belongs to acrylamide thickeners, adhesives.
Methylene diacrylamide N, N' -methylene diacrylamide (Methylene diacrylamide) can be used as a cross-linking agent for the preparation of polyacrylamide gel and the separation of biomolecular compounds (protein, polypeptide, nucleic acid). It has substituted acrylamide, so it has some toxicity. It can slightly irritate the eyes, skin and mucous membranes and affect the central nervous system. Direct contact with human body for a long time should be avoided. Do not inhale powder and use clean water by mistake.
The preparation methods
A preparation method of N-N '-methylene diacrylamide is described in the following steps:
(1) Add 245kg water to the reactor, start stirring, and heat up to 70℃;
(2) 75kg acrylamide and 105kg formaldehyde were added at the same time. The addition amount of p-hydroxybenzoyl methyl ether was 100 ~ 500ppm. The mixture was stirred for 1 hour at 40℃ for full reaction.
(3). Then 75kg acrylamide and 45kg catalyst hydrochloric acid were added, heated to 70℃ under stirring, reacted for 2 hours, and cooled for 48 hours.
(4). The product was filtered and dried at 80℃ to obtain n-N '-methylene diacrylamide product.
use
1. Used as an important material for separation of amino acids and an important raw material for photosensitive nylon or photosensitive plastics
2. Can be in oil field drilling operation and building used as plugging agent in the grouting operation, can be in acrylic resin and the adhesive has been used as a crosslinking agent USES synthetic nylon and used as a photosensitive photosensitive plastic raw materials, grouting materials, also used in photography, printing, plate making, such as mixed with the acrylamide used in preparation of polyacrylamide gel, used in protein and nucleic acid electrophoresis.
