Provided is a novel fiberglass binder comprising a polycarboxy polymer and a polyol. The amount of polycarboxy polymer and polyol contained in the binder is such that the ratio of equivalents of hydroxyl groups to carboxy groups is preferably in the range from from about 0.6 / 1 to 0.8 / 1. It is further preferred that the molecular weight of the polycarboxy polymer is less than 10,000, and more preferably less than 5000.

The present invention relates to a process for the production of five-membered or six-membered cyclic ethers, in particular of anhydropolyols, by acid-catalysed cyclodehydration of polyols that contain at least two hydroxyl groups with a spacing enabling ring formation-that is to say, preferably with a spacing of 4 or 5 C atoms. The invention is directed in particular towards the production of anhydrotetritols, anhydropentitols and, particularly preferred, anhydrohexitols, from tetritols, pentitols and hexitols, respectively.

The invention provides a method for preparing ethanediol from polyhydroxy compounds comprising starch, hemicellulose, cane sugar, glucose, fructose and fructosan. The method comprises the following steps of: taking the polyhydroxy compounds as reaction raw materials, and taking metals, carbides, nitrides, and phosphides of transition metals in families VIII, IX and X, such as ferrum, cobalt, nickel, ruthenium, rhodium, palladium, iridium, platinum, molybdenum and tungsten as catalytic active components to form a polymetallic catalyst; and performing further catalytic conversion under a hydrothermal condition that the temperature is 120 to 300 DEG C and the hydrogen pressure is 1 to 13 MPa to prepare the ethanediol from the polyhydroxy compounds with high efficiency, high selectivity and high yield. The method for preparing the ethanediol from the polyhydroxy compounds has the outstanding advantages of renewable raw materials, environment-friendly reaction process, and atom economical efficiency. Simultaneously, compared with other techniques taking biomasses as the raw materials, the method has the advantages of simple process and high yield.

The invention provides a liquid pharmaceutical formulation which does not include NaCl and comprises more than 20 mg of a polyol and at least about 100 mg / mL of a human anti-TNF-alpha antibody, or antigen-binding portion thereof. The invention provides a high concentration antibody formulation having long-term stability and advantageous characteristics for subcutaneous administration.
