An integrated and improved process for the production of acrylic fibers is described, specifically a process that starts from the comonomers and reaches the spinning step obtaining the final fiber.

Integrated and improved process for the production of acrylic fibers

A process for the production of acrylic fibers, in particular a spinning process for obtaining precursor fibers of carbon fiber by the wet spinning of a polymer solution in an organic solvent and the relative apparatus.

High-speed process for producing acrylic fibers and relative apparatus

An integrated and improved, single-step, process for the production of a carbon fiber precursor is described, specifically a process which starts from the comonomers and reaches the spinning step, obtaining the final precursor fiber.

Single-step process for the production of a carbon fiber precursor

An optimized process for the preparation of a spinning solution for the production of acrylic fiber precursors (PAN) of carbon fibers and an optimized process for the production of carbon fibers from said acrylic precursor (PAN), are described.

Optimized process for the preparation of a spinning solution for the production of acrylic fibers precursors of carbon fibers and the relative carbon fibers

A process for the preparation of a homogeneous spinning solution for the production of acrylic fibers, which includes: preparing an aqueous suspension of homopolymer or copolymer of acrylonitrile through the polymerization of monomers in aqueous suspension, removal of the unreacted monomers, filtration and washing of the aqueous suspension, obtaining a filtration cake; dispersing the filtration cake; and evaporating the dispersion of polymer or obtaining the homogeneous spinning solution.

Simplified process for the production of acrylic fibers

A process for the preparation of a homogeneous spinning solution for the production of acrylic fibers comprising:

Process for the production of acrylic fibers

Polyaminoacid builders or co-builders having the general formula: ##STR1## that are useful in the formulations of detergents are disclosed. Preferred detergent formulations contain from 5 to 50 percent by weight of the polyaminoacid builder, preferably polyaspartic aicd or polyglutamic acid, together with surface-active agents, aluminosilicates and other detergent additives.

Polyaminoacids as builders for formulations of detergents

The invention relates to modified materials based on polyacrylonitrile having amidic groups on their surface. The modification gives the material greater hydrophilic characteristics improving its comfort properties. In addition, it permits the polyacrylonitrile to be dyed also with acidic dyes thus making it possible for it to be used for the preparation of yarns mixed with natural fibres, such as wool for example. The process for their production involves treatment of the material with enzymes of the nitrile hydratasis class obtained from Brevibacterium imperiale.

An in vitro process for preparing 6((1R)-hydroxyethyl) penem acids by hydrolyzing the carboxylic ester derivative thereof using an enzyme capable of selectively hydrolyzing the ester group at the 3-position of the carboxylic acid ester using an esterase, acylase or lipase enzyme, wherein the enzymatic hydrolysis is effected at a pH in the range of from 5 to 8 and at a temperature in the range of 20.degree. C. to 40.degree. C.

Process for the preparation of penems

A cobalt based catalyst, and the method for preparing it, are disclosed. The catalyst is obtained from the reaction between NaCo(CO).sub.4 and s-trichloro triazine and is advantageously used in the processes of carbonylation of naphthalene mono- and disulfonates in order to yield naphthalene esters and acids.

Catalyst for carbonylating naphthalene mono- and disulfonates and

This invention relates to use of polyaminoacids as builders or co-builders in the formulation of detergents. These polyaminoacids, which are highly efficient as complexing agents, have good resistance to heat and stability to pH and are entirely biodegradable, have been chosen among those having the general formula: ##STR1## with substituents which are defined in the following description. The formulations of detergents contain, apart from the above builders, surface active agents, alumina-silicates and additives chosen from neutral salts, enzymes, bleaching agents, stabilizers, anti-foaming agents, perfumes, bactericides.

4-substituted anthracyclinones and their preparation

A process for preparing a compound of formula I: ##STR1## wherein R.sub.1 represents a hydroxy protecting group and R.sub.2 represents a carboxy protecting group, which comprises:
