Abstract:
A compound represented by the following formula (1) and a method for producing the same, and a composition, a composition for optical component formation, a film forming composition for lithography, a resist composition, a method for forming a resist pattern, a radiation-sensitive composition, a method for producing an amorphous film, an underlayer film forming material for lithography, a composition for underlayer film formation for lithography, a method for producing an underlayer film for lithography, a resist pattern formation method, a circuit pattern formation method, and a purification method. wherein R 1  is a 2n-valent group of 1 to 60 carbon atoms or a single bond; R 2  to R 5  are each independently a linear, branched, or cyclic alkyl group of 1 to 30 carbon atoms, an aryl group of 6 to 30 carbon atoms, an alkenyl group of 2 to 30 carbon atoms, a group represented by the following formula (A), a group represented by the following formula (B), a thiol group, or a hydroxy group, wherein at least one selected from the group consisting of R 2  to R 5  is a group selected from the group consisting of a group represented by the following formula (A) and a group represented by the following formula (B); m 2  and m 3  are each independently an integer of 0 to 8; m 4  and m 5  are each independently an integer of 0 to 9, provided that m 2 , m 3 , m 4 , and m 5  are not 0 at the same time; n is an integer of 1 to 4; and p 2  to p 5  are each independently an integer of 0 to 2: wherein each R 6  is independently an alkylene group of 1 to 4 carbon atoms; and m′ is an integer of 1 or larger, and wherein R 6  is as defined above; R 7  is a hydrogen atom or a methyl group; and m″ is 0 or an integer of 1 or larger.

Claim (Index 34):
A purification method comprising the steps of:\n obtaining a solution (S) by dissolving one or more kinds selected from the group consisting of the compound according to  claim 1  in a solvent; and extracting impurities in the compound by bringing the obtained solution (S) into contact with an acidic aqueous solution (a first extraction step), wherein the solvent used in the step of obtaining the solution (S) comprises a solvent that does not mix with water.
