In this application is disclosed a process for producing 3,9-bis(2-chloroethyl)-2,4,8,10-tetraoxaspiro&lsqb;5.5&rsqb;undecane comprising a step of reacting acrolein, pentaerythritol, and hydrogen chloride at one step, according to which the compound can be obtained conveniently in high yields.

Process for producing spiro acetal derivative

Provided is a novel surfactant which is less irritating to the skin or the mucous membrane than prior art surfactants, which exhibits excellent conditioning effects and fabric softening effects, and which can be widely used in a toiletry or detergent composition. Basic amino-acid derivatives or salts thereof obtained by reacting glycidyl ethers with basic amino acids or salts thereof are incorporated into a toiletry or detergent composition or a conditioning agent.

Surfactant, and toiletry or detergent composition containing the same

Disclosed herein is a polyether acrylamide derivative of the following general formula (I): ##STR1## as well as an active energy ray curable resin composition comprising at least one polyether acrylamide derivative of the above general formula (I) and a cured product produced by curing such an active energy curable resin composition with active energy rays.

Polyether acrylamide and active energy ray curable resin composition

Here is disclosed a water-insoluble pyrogen adsorbent composed of a polymer possessing amide groups optionally modified, said polymer being, e.g., a poly amino acid, a nylon, on a polyacrylamide.

Pyrogen adsorbent containing amide groups

Artificial hair comprising a polyamino acid having a degree of polymerization of 50-10,000, and having pendant mercapto or disulfide groups.

Artificial hair comprising poly alpha amino acid having pendant mercapto

A liquid crystal compound of the formula: ##STR1## wherein R.sup.1 is an alkyl group, X is chloro or bromo, and R.sup.2 is a branched-alkyl group; and the carbon atom marked with an * is an asymmetric carbon atom.

Smectic liquid crystal compound and liquid crystal compositions

When an alcohol or its hydrochloric or hydrobromic acid ester is held at 50.degree. to 200.degree. C and 10 to 500 atmospheres in the presence of hydrogen, carbon monoxide, the amide of a carboxylic acid, and a carbonylation catalyst, an aldehyde having one more carbon atom than the alcohol or ester is formed in a good yield. If the amide has at least one active hydrogen atom on its amide nitrogen, it further reacts with the aldehyde and carbon monoxide to form an N-acylamino acid by the reaction of U.S. Pat. No. 3,766,266.
