    Abstract: An optimized system and process for heating wood using a microwave heater. The optimized system/process directs microwave energy towards different regions of the wood at different times during heating. In certain situations, microwave energy is introduced into the heater using microwave launchers and the system includes one or more microwave switches that control distribution of microwave energy to the microwave launchers so that two adjacent and/or opposing microwave launchers do not simultaneously introduce microwave energy into the heater. The optimized heating process also includes heating wood using a plurality of sequential heating cycles carried out at different conditions. For example, at least one of the heating cycles can be carried out at a lower input rate of microwave energy and/or at a lower pressure than one of the previous heating cycles.

    Abstract: A commercial scale microwave system that includes a heater having enhanced heat distribution and minimized void space. The enhanced heat distribution can be provided by a unique launcher and/or reflector configuration disposed in the interior of the microwave heater. The microwave system can be operated to prevent the wood from both overheating (which results in scorching) and under-heating (which results in inadequate drying and/or inadequate thermal- modification). The microwave heating system can provide enhanced microwave energy distribution for large quantities of wood, even large quantities of wood heated under vacuum and/or in the presence of one or more chemical reagents.

    Abstract: A microwave heater capable of heating a bundle of wood and equipped with an optimized system for introducing microwave energy into the heater is provided. Also provided is an enhanced system for launching and dispersing within the heater. The system uses one or more TM ab microwave launchers to emit microwave energy in the interior of the microwave heater in a TM ab mode, where a is 0 and b is an integer between 1 and 5. The TM ab launchers can be configured to emit microwave energy through an open outlet that faces generally parallel to the nearest wall of the heater. In certain situations, it can be advantageous to use at least two TM ab microwave launchers having open outlets that face towards one another. In certain situations, it can be advantageous to use at least two TM ab microwave launchers located on generally opposite sides of the microwave heater. In certain situations, the system can also include one or more moving reflectors for dispersing microwave energy emitted from the TM ab microwave launchers.

    Abstract: Disclosed is a 4-step process for the preparation of alkyl esters of 1-methylcyclopropanecarboxylic acid which comprises the steps of (1) converting η-butyrolactone to α-methyl-η-butyrolactone; (2) converting the α-methyl-η-butyrolactone from step (1) to an alkyl 4-halo-2-methyl-butyrate; (3) producing a xylene solution of the alkyl 4-halo-2-methyl-butyrate; and (4) contacting the xylene solution of the alkyl 4-halo-2-methylbutyrate from step (3) with an alkali metal alkoxide under conditions to temperature and pressure which causes vaporization of (i) an alkanol as it is fomred and (ii) an alkyl 1-methylcyclopropanecarboxylate as it si formed from the alkyl 4-halo-2-methylbutyrate. Also disclosed are processes whereby the alkyl 1-methylcyclopropanecarboxylate, prepared as described above, is converted to 1-methylcyclopropylamine.
