  fuels. However, their combined emissions from the domestic burning of coal and wood would contribute only a few percent to annual U.K. emission estimates. Emissions of PAHs and PM10 were major contributors to U.K. national emission inventories. Major emissions were found from the domestic burning for Cl1,2,3DFs, while the contribution of PCDD/F-sigmaTEQ to total U.K. emissions was minor.

  本文介绍了当煤和木材经过受控燃烧实验时针对一系列持久性有机污染物（POPs）得出的排放因子（EFs），旨在模拟空间供暖的家庭燃烧。排放了各种各样的持久性有机污染物，煤炭的排放量高于木材的排放量。对于颗粒物，PM10（大约10 g / kg燃料）和多环芳烃（对于sigmaPAHs大约100 mg / kg燃料）获得了最高的EF。对于氯化物，多氯联苯（PCB）的EF最高，而多氯萘（PCN），二苯并-对-二恶英（PCDD）和二苯并呋喃（PCDF）的丰度较低。对于sigmaPCB，EF大约为1000 ng / kg燃料，对于sigmaPCNs大约为100s ng / kg燃料，对于sigmaPCDD / Fs大约为100 ng / kg燃料。该研究证实，一氯化至三氯化二苯并呋喃Cl1,2,3DFs是低温燃烧过程（如煤炭和木材的国内燃烧）的有力指标。结论是，在固体燃料燃烧期间通常形成许多PCB和PC

  In a process in which a poly (arylene sulfide) is synthesized by reacting a dihaloaromatic compound and an alkali metal sulfide in a polar organic solvent, the curing ability of the product polymer may be significantly enhanced by introducing a small proportion of a hydroxyl group-­containing polyhaloaromatic compound to the reaction mixture when a conversion of at least 60% has been achieved with respect to the dihaloaromatic compound present in the reac­tion mixture. The product polymer may be advantageously employed in various molding, forming or coating processes to provide the produced articles with increased strengths. The hydroxyl groups introduced into the polymer enable the polymer to be modified, if desired.

  In a process for preparing a polyarylene sulfide by reacting an alkali metal sulfide and at least one dihaloaromatic compound in an organic amide solvent at an elevated temperature: a highly pure anhydrous alkali metal sulfide reactant having a purity of at least 95% by weight and a content of alkali metal hydrosulfide impurity of not greater than 2% by weight is employed. The water is deliberately added in a proportion of 0.1 to 0.8 moles per each mole of the alkali metal sulfide used in the process. The alkali metal sulfide reactant is charged in a concentration of 2.5 to 5 moles per liter of the reaction mixture. The deliberate addition of water enables one to omit a dehydration stage which has been desirably or rather necessarily effected to obtain a satisfactory polymer product where a hydrous alkali metal sulfide reactant is employed. The improved process of the invention provides a highly pure polyarylene sulfide product having a relatively increased molecular weight and a decreased content of by-product oligomers.
