Processes For The Production of Acrylic Acids and Acrylates

A process for producing an acrylate product, comprising the steps of:

• dehydrating a crude alkylenating stream to form a dehydrated crude alkylenating stream comprising at least 55 wt. % alkylenating agent;
• reacting the dehydrated alkylenating stream with acetic acid from an acetic acid feed stream in a reactor to form a crude acrylate product stream comprising the acrylate product, an alkylenating agent and acetic acid;
• and
• recovering the acrylate product.

A process for producing an acrylate product, comprising the steps of:

• dehydrating a crude alkylenating stream to achieve at least 60 wt. % formaldehyde in the dehydrated stream;
• reacting the dehydrated alkylenating stream with acetic acid from an acetic acid feed stream in a reactor to form a crude acrylate product stream comprising the acrylate product, an alkylenating agent and acetic acid;
• and
• recovering the acrylate product.

A process for producing an acrylate product, comprising the steps of:

• dehydrating a crude alkylenating stream to remove at least 15% of the water therefrom;
• reacting the dehydrated alkylenating stream with acetic acid from an acetic acid feed stream in a reactor to form a crude acrylate product stream comprising the acrylate product, an alkylenating agent and acetic acid;
• and
• recovering the acrylate product.
